In this proposed research, the time response of a beam structure
containing a sharp crack and subjected to a time varying loading is
considered. In overcoming known crack surface closure difficulties, a
process of material homogenization is proposed aiming at establishing
the effective orthotropic, non linear mechanical response of the cracked
domain. Robust geometry meshing algorithms are developed and used in
conducting fundamental numerical finite element homogenization studies.
Crack surface closure effects are addressed and comparisons to known
analytical, numerical and experimental results will be carried out. In
addition to the above, an eigenvalue approach as well as a time
dependent response method are considered as a means of evaluating the
response of cracked structures.
