M.S. (thesis and non-thesis options), Ph.D., Graduate Certificates in Mechatronics and Computational Thermal/Fluid Dynamics
The Department currently offers two graduate degree programs; the M.S. and Ph.D. degrees in Mechanical Engineering. These are primarily research degrees. Although in some cases the M.S. degree may be based on primarily course work and no thesis, it nevertheless requires research exposure. Our goal is to broaden the graduate degree offerings to meet the needs of industry and local professional engineers for updated skills. To this end the Department has developed two specialized graduate certificate programs which consist of four courses each. These programs which have been approved and are currently running are in the Computational Thermal/Fluid Dynamics (CTFD) and the Mechatronics areas. Two more certificate programs are under consideration, one in Computational Structural Mechanics and one in Biomechanics. The UMBC Mechanical engineering graduate program hosts more than 70 active graduate students. Enrollment is approximately divided evenly with 50 percent in the Ph.D. program and 50 percent in the M.S. program.
The mission of the graduate program in Mechanical Engineering is to conduct cutting edge engineering science research and provide students at the graduate level with a strong fundamental education in mechanical engineering to prepare them for life-long contributions to the field, and for leadership positions in academics, industry, and government agencies and laboratories. The M.S. program focuses on providing students advanced training in the fundamental sciences and technology of Mechanical Engineering to enable them to pursue careers in applied research and development. The Ph.D. program focuses on training engineering scientists who will devote their professional careers to the development of fundamental knowledge and technology from which applications will emerge.
Most of the graduate courses in mechanical engineering are offered in the late afternoon or early evening to enable part-time working students from local industries and government laboratories to participate in the program. The university allows, and the department encourages, qualified students to enroll in graduate courses as non-degree-seeking, special advanced students. Changing to degree-seeking, regular graduate student status is encouraged, should the student so qualify. The department offers courses, and its faculty and students conduct research in the following four areas of specialization:
Biofluid dynamics, bioheat transfer, biomaterials, and biomechanics. Biomechanical Engineering (BIOM) studies the fluid dynamics, thermal transport, elastic and dynamic process, and materials in living systems. The research efforts focus on development of fundamental and applied engineering knowledge related to biomechanical systems, and the application of engineering principles toward the design and development of biological materials, treatment of diseases, and performance of biomedical devices. Significant research efforts are aimed at developing a fundamental understanding of aging and disease processes in living systems. Faculty in this area are conducting interdisciplinary research in the following areas:
(1) Understanding the properties of hard biological tissues (i.e. bone, dentin and enamel), the engineered materials that replace them, the interfaces between hard tissues and biomaterials, and development of new manufacturing processes that can be applied to biological materials and/or biomaterials in dental and medical treatments.
(2) Understanding the mechanical behavior of deformable particles, including living cells, and the influence of hydrodynamic forces and applied external forces on their behavior, and high throughput measurements of cell mechanical properties
(3) Investigating the heat and mass transfer in magnetic nanoparticle hyperthermia and photothermal therapy using gold nanoshells/nanorods in cancer therapy, targeted brain cooling using an interstitial cooling device, and bacterial disinfection in endodontics using laser or heating catheters.
(4) Surface modifications to biomaterials to prevent wear and corrosion; micro- and nano-structural modifications to increase fatigue and fracture resistance; understanding the structure/function changes in human arteries that occur as a result of aging or disease, and responses to interventions used to treat heart disease.
The Biomechanical Engineering faculty in the Mechanical Engineering Department at UMBC maintain close collaborative relationships with other institutions in the Baltimore-Washington area, including the University of Maryland Medical and Dental Schools, the Johns Hopkins University Medical School, the U.S. Food and Drug Administration (FDA), and the National Institute of Standards and Technology (NIST).
Design, Manufacturing and Engineering Systems
Advanced manufacturing processes, mechatronics, mechanical design, dynamics, vibrations, controls, kinematics, mechanisms, robotics, and virtual reality.
The Design, Manufacturing, and Systems (DEMS) area encompasses the study of design, computer-aided design, mechatronics, design for manufacturing, traditional and non-traditional manufacturing processes, manufacturing processes in dental and medical practices, computer-aided manufacturing, multibody system dynamics, control systems, compliant mechanisms, virtual reality simulation, computational kinematics, robotics, electro-mechanical systems, manufacturing systems, production systems, dynamics and vibrations of mechanical systems, vibrations of continuous systems, cable dynamics, finite element modeling, modal testing, model updating, structural damage detection, system identification, energy harvesting, and system optimization. There are five faculty members who have primary research specialization in Design, Manufacturing, and Systems.
Solid Mechanics and Materials Engineering
Solid Mechanics and Materials Engineering (SMME) encompasses the computational, analytical, and experimental solid mechanics, the mechanical behavior of materials and materials science, and engineering. There are six faculty members who specialize in various facets of these areas.
Research projects currently conducted by faculty include fatigue crack growth, nanoindentation, mechanical behavior of hard tissues and structure-property relationships; finite elements applied to fracture mechanics, micro-mechanics of composites, modeling of composites (unidirectional, laminate and woven polymer and ceramic matrix composites); mechanics of water filtration and temperature sensitive biochemical reaction, kinematics of accurate surface feature tracking in rugged 3D terrain, effect of post-fabrication surface treatment on permeability and corrosion resistance of reinforced concrete; responses and constitutive modeling of emerging materials (nano-materials, polymers and newly developed metal alloys) over wide range of strain rates and temperatures, study of anisotropic plastic responses of metals and constitutive modeling of the observed responses, grain-size reduction using severe plastic deformation (milling and ECAP) and investigations of reduced grain-size metals; modeling and design of biomedical devices, surface modification and wear of artificial joints, structure/function relationships in aging and diseased human tissue; fracture and fatigue of biomaterials microscale specimen testing, carbon nanotube infused multi-length scale composites, and friction stir welding
Thermal-Fluids Sciences involves the application of experimental techniques and mathematical methods based on principles from physics, fluid and gas dynamics, and heat transfer to the development and operation of energy conversion systems, such as solar panels, wind turbines, and internal combustion engines. Research projects currently conducted by faculty in the thermal fluid sciences involve heat and mass transport processes, microfluidics, fluid dynamics, hydrodynamic stability theory and fluid-structure interaction problems, many that are associated with biological and medical applications. Employing a combination of experimental methods with mathematical models, we are investigating the effects of fluid dynamics and heat and mass transfer on strategies for the delivery of therapeutics agents within tissue and through the circulatory system, the design of biomedical devices for the identification and separation of specific biological cells, and for manufacturing novel materials and coatings with localized material properties. Four faculty are conducting interdisciplinary research in the following areas:
(1) Mechanical behavior of deformable particles, including living cells, and the influence of hydrodynamic forces and applied external forces on their behavior; high throughput measurements of cell mechanical properties.
(2) Heat and mass transfer in magnetic nanoparticle hyperthermia and photothermal therapy using gold nanoshells/nanorods in cancer therapy; targeted brain cooling using an interstitial cooling device; bacterial disinfection in endodontics using laser or heating catheters.
(3) Transport phenomena, phase change, chemical reaction kinetics in material processing (directional solidification, chemical vapor deposition, ribbon growth on substrate); nanomaterial transport and deposition in porous structure.
(4) Hydrodynamic stability and transition to turbulence, non-Newtonian fluid flow, heat and mass transfer, numerical methods and computer simulations, engineering education.
Graduate Certificate Programs
The mechanical engineering department offers two graduate certificate programs. These programs consist of a sequence of four graduate courses in a highly focused technical area. Each certificate program is designed for students to attain professional expertise in the respective technical field in a minimum amount of time and without a commitment to a long-term educational objective. However, the certificate programs can be used as a stepping-stone to any of the masterís programs or the doctoral degree. All courses taken for the certificates are regular graduate courses and count toward the higher degree programs.
CERTIFICATE IN MECHATRONICS
ENME 811M: Mechatronics System Design
ENME 605: Advanced Systems Control
ENME 812P: Analog and Digital Electronics

Students with other bachelorís degrees may be required to make up appropriate undergraduate courses to have the background for the required graduate courses. Each of these certificate programs form one of the engineering tracks of the M.S. in Engineering Management program and, thus, can be used to satisfy some of the requirements of this and the M.S. in Mechanical Engineering, as well as the Ph.D. in Mechanical Engineering.
The masterís degree program is focused on providing students with advanced training in the fundamental sciences and technology of mechanical engineering to enable them to pursue careers in applied research and develop new products and processes. The graduate may find employment in government and industrial laboratories, advanced technology firms or teach in community colleges. The masterís degree program has a thesis and a non-thesis option.
Master of Science (Thesis Option)
This degree will prepare students for employment in research-oriented positions, as well as serve to form a base for further doctoral studies. A minimum of 24 course credits at the graduate level or equivalent, plus six credits of ENME 799, Masterís Thesis Research, culminating in a defensible thesis is required.
Master of Science (Non-Thesis Option)
A minimum of 30 course credits will be required for this degree. This professional degree program is primarily intended for part-time students. No thesis is required, but the student is required to register for one credit of ENME 799 leading to a scholarly paper and to pass the masterís comprehensive examination.
UMBC undergraduate students with a GPA of 3.25 at the completion of their junior year will be encouraged to combine their baccalaureate studies with the master of science and a thesis. In an approved plan of study, the student may qualify to count a maximum of nine credit hours of senior electives toward the fulfillment of the masterís degree.
The doctoral program is aimed at training engineering scientists who will devote their professional careers to the developing of fundamental knowledge and technology from which applications will emerge. These engineering scientists will fill the research positions in government and industrial laboratories, as well as teaching and research positions in universities. A minimum of 42 course credits beyond the bachelorís degree is required for the doctorate. Exceptional students with a bachelorís degree may choose to go directly to a doctoral program without first earning a masterís degree. Students entering with a masterís degree may apply a maximum of 24 graduate course credits from their masterís degree program. Doctoral students must have a minimum of 12 credit hours of ENME 899: Doctoral Dissertation Research, culminating in an acceptable, defensible doctoral dissertation.
All doctoral students must pass the qualifying examination before or during the second semester of studies. The student is advanced to doctoral candidacy after the completion and successful presentation of a doctoral dissertation proposal (the candidacy exam) to the studentís advisory committee. The candidacy exam is to be presented no later than the end of the studentís third semester in residence. All doctoral candidates must enroll for a minimum of six credit hours of ENME 899: Doctoral Dissertation Research in each semester of residence. Doctoral candidates are required to present at least one seminar lecture/talk per year. Presentation of a paper at a technical conference will count as a seminar.
Program Admission Requirements
The basic admission requirement for graduate studies in mechanical engineering is a bachelorís degree in mechanical, aerospace, civil or chemical engineering. Students with undergraduate backgrounds in electrical engineering, physics, chemistry or mathematics may enter the program contingent on fulfilling a minimum number of undergraduate prerequisites to graduate courses in mechanical engineering (this number depends on the studentís credentials).

Facilities and Special Resources
The department is located in the Engineering and Computer Science (ECS) Building and has developed research and instructional laboratories with state-of-the-art equipment, instruments and machines. The department continues to maintain research facilities in the Technology Research Center at UMBC. Special research facilities are dedicated to studies in the three areas of specialization of the department.
The design and manufacturing systems program includes laboratories in robotics, mechatronics and manufacturing:
- The Robotics Laboratory provides facilities for studying and analyzing advanced manipulators and dexterous grippers. The current main thrust of research activities is grasping mechanics and compliance control. The laboratory is equipped with several robots, including a Puma 500 series robot fitted with a three-pneumatic-finger gripper and a Seiko D-Tran robot with a parallel pneumatic gripper. Transducers, computers, Silicon Graphics workstations and peripheral equipment are available in the laboratory.
- The Advanced Manufacturing Processes Laboratory is located in Rooms 110 and 111 of the ECS Building and occupies about 2,300 square feet of floor space. The major equipment contained within the laboratory includes an OMAX Model 2652 CNC Abrasive Waterjet, a Fadal CNC Vertical Machining Center and a Methods Slant 50 CNC Turning Center. In addition, the laboratory contains two Dyna CNC mills, a Dyna CNC lathe and supporting manual equipment, including a table grinder and vertical and horizontal band saws. Computer equipment includes three Silicon Graphics Indigo workstations, a Power Macintosh 6500, a Gateway Pentium and a laser printer. The lab also contains a Hommel T8000 Surface Roughness Analysis System that is complemented with a Form 1000 Measuring Instrument that is capable of form measurements and analysis.
- The Mechatronics Laboratory allows the facility to design, analyze and experimentally validate new and innovative products that typically involve sensors, actuators and controls. The laboratory is equipped with PC-based, real-time control computers, general-purpose instrumentation, an HP 3566A Spectrum Analyzer,INTEL-based controllers, sensors, ultra-high-speed digital controllers and magnetic field generators.
- The Biomechanical Engineering Program is supported by research facilities in the Laboratory for Implantable Materials and Biomechanics, the Living Structures Laboratory and the Biofluid Mechanics Laboratory.
- The Laboratory for Implantable Materials and Biomechanics, principally focuses on the investigation of the mechanical properties of both hard and soft tissues (bone, ligament and tendon) and implantable materials to determine the structure function correlation of the materials to their macro-mechanical behavior. The laboratory is equipped with an MTS 851 materials testing machine, Elite 3-D kinematic analysis system, and associated computer, biochemical and histological support equipment.
- Tony Farquharís Living Structures Laboratory uses engineering mechanics to study the effect of natural forces on living and life-like machines, including plants, animals and robots. For example, computer-aided video-photography was used to measure the dynamic frequency response of wheat, and the department wind tunnel was used to study the rodynamics of the same plants. Other topics of interest include the failure mechanics of articular cartilage and tunable vibration absorbers for use in micro-gravity. An educational project involving several undergraduates led to the development of a dancing robot that performed in several cities. Off-site research has been conducted with the United States Department of Agriculture and with the International Maize and Wheat Improvement Center in Mexico.
- The Biofluid Mechanics Laboratory is dedicated to the study of the mechanical behavior of suspensions of red blood cells and other flexible capsules. Experiments are conducted to determine the relationship between the flow conditions and the mechanical properties of these membranes. The laboratory is equipped with a computerized cell transit analyzer, a Coulter counter for mean red cell volume measurement, a cardiac phantom that duplicates the pressure variations within the left ventricle, an Artholux II optical microscope and other support equipment.
Other research and teaching laboratories in the department include:
- The Inelastic Impact Dynamics Laboratory, focused on the study of the behavior of materials (metals, ceramics, composites, biological and rock-like materials) at high rates of loading, to understand the mechanics of plastic wave propagation and damage due to impact in these materials, as well as to investigate penetration mechanics.
- The Non-Linear Material Characterization Laboratory is used for investigating the non-linear behavior of metals and rock-like biological and composite materials under triaxial loading in controlled pressure-temperature-humidity environments. This laboratory recently has acquired two MTS testing systems, one with a 110 kips tension-compression cyclic loading capability, and the other with 55 kips tension compression coupled with 20 in-kips torsion capabilities. These are computer-controlled with automatic data acquisition system. The laboratory also has an X-ray diffraction system and an electron microscope.
- The Phase Change Heat Transfer Laboratory is used to study fundamental processes associated with boiling heat transfer, with emphasis on the study of the mechanisms that lead to critical heat flux and the phenomena associated with the boiling of mixtures.
- The Computational Fracture Mechanics and Composites Laboratory (CFMC Lab) offers individual access to high-end Unix computing workstations and other PC systems used in conducting computational studies in the areas of fracture and composite materials. The research conducted in the lab is funded through government agencies such as the National Science Foundation, local industry and the state of Maryland through the Maryland Industrial Partnerships Program (MIPS). Current research includes computational studies on the mechanical and fracture behavior of woven polymer and ceramic matrix composites and finite element simulations on thermo-mechanical deformations induced during the fabrication of high-end rapid prototyping molds. The lab also is used for software development studies on interactive engineering that led to the development of the DENDRO technology transfer finite element software, which features a state-of-the-art Graphical User Interface (GUI).
- The Virtual Reality &Mechanisms Laboratory (VRML, accessible at http:/www.umbc.edu/ engineering/me/vrml/index.html) has been established to provide undergraduate and graduate students, the research and education on mechanism science, computational kinematics, design of machine systems, and application of advanced virtual reality techniques in engineering design. Current research interests include: (1) Automatic and interactive design of compliant mechanisms, (2) Virtual reality applications in design, manufacturing, and bio/nantechnologies, (3) Computer-aided mechanism design, (4) Computational and theoretical kinematics and robotics and (5) Solving polynomial systems with resultant elimination and homotopy continuation methods.
The Office of Information Technology provides six UNIX-based systems, one of which is exclusively for high-speed processing. The department has one computer lab providing PCís and workstations for undergraduate students. Most researchers have workstations and networked PCs available in their respective labs. The networked PC is attached to the CAD lab server and provides all the software necessary for research needs. The workstations are attached to an engineering network consisting of a Sunbased and SGI-based operating system. The workstations are SGI Elan stations, and the Suns are Sparctstations. Pertinent engineering periodicals and technological publications are available on campus as well as on the inter-library loan network. Assistance for the acquisition of reference materials may be obtained from the university library.
Graduate teaching assistantships (GTA), graduate research assistantships (GRA) and graduate fellowships are available in the Department of Mechanical Engineering. Graduate fellowships may include Northrop Grumman Fellowships, GAANN Fellowships and the Meyerhoff Graduate Fellowships. It is departmental policy to give priority for financial aid to students committed to pursuing the doctorate at UMBC. Exceptional masterís students also may be considered for financial aid. However, it must be emphasized that graduate teaching assistantships are awarded only to the best applicants, as judged by the departmental graduate committee. Graduate research assistantships are awarded by the professor in charge of the research project, although admission into the graduate program still goes through the departmentís graduate committee.
Graduate Teaching Assistantships
Several GTA positions are available in the state-supported budget of the department. These are awarded to qualified and deserving students to assist the faculty in its teaching responsibilities. The UMBC Graduate School establishes the policies on the qualifications for level of support, the amount to be paid and the benefits that accompany the appointment. The department assigns the responsibilities the GTA must assume. More specifically, for the academic year 2006-07, the minimum stipend for a doctoral student awarded a GTA was $14,350. In addition to this stipend, the student receives remission of tuition for a maximum of 10 credits each semester, fall and spring, plus health benefits. In return for this assistantship, the GTA is expected to provide the equivalent of 20 hours per week from August 17 to June 15 of curriculum- related services to the department. The GTA may be assigned to lead in recitation and discussion periods, assist in laboratory courses, grade papers and reports for courses and other services required by the department to accomplish its teaching responsibilities. GTAís are expected to participate in at least one credit hour of dissertation research each semester (ENME 799 or ENME 899) under the supervision of their advisor.
The mechanical engineering graduate committee evaluates all applications for admission to the mechanical engineering graduate program and makes the selection for awarding these assistantships in a competitive manner on the basis of the following criteria: (a) potential for completion of the doctorate; (b) faculty needs for teaching and other tasks; and (c) ability of the student to undertake the needed tasks for a teaching assistant, e.g. skill and experience in laboratory work, design and computers. Assignment of teaching duties will depend on the GTA. To receive a GTA, international students must possess a required level of proficiency in verbal English.
Graduate Research Assistantships
GRA appointments are made to support research grants/contracts developed by faculty members. In a research project, the GRA becomes a team member dedicated to accomplishing and attaining certain research objectives. Therefore, the appointment of the GRAs is left entirely to the discretion of the faculty in charge of the research grant/contract. The remuneration for the GRA, stipend, tuition remission and health benefits are comparable to that of the GTA. The amount of work expected of the full GRA is also 20 hours per week. It must be emphasized that this appointment to work on a research contract or grant is principally to undertake contracted tasks that may coincide with the doctoral dissertation or masterís thesis work of the student. It is also important to note that if students abrogate their commitments to the GRA or GTA appointments that they have accepted, further financial aid is not guaranteed.
