ON THE 3-DIMENSIONAL INTERFACE CRACK PROBLEMS IN PERIODIC 2-LAYERED COMPOSITES

Within the framework of the linear thermoelasticity with microlocal pa rameters the solutions of some three-dimensional interface crack probl ems in a two-layered periodic space are obtained. Effective results ha ve been achieved through the use of similarity in governing equations of the homogenized model for the laminated body and transversely isotr opic elastic solid. Some specific examples concerning interface crack problems have been considered and discussed from the point of view of fracture theory.
