INTERACTION OF PERIODIC SYSTEM HETEROGENEOUS INCLUSIONS AND COHESIVE CRACKS UNDER LONGITUDINAL SHEAR

The elastic medium weakened by a periodic system of circular holes filled with washers from homogeneous elastic material is considered. The surface of circular holes is covered by a cylindrical film. Medium (binder) is weakened by two periodic systems of rectilinear cracks with bonds between the faces in end zones. General representations describing the class of problems with periodic stress distribution out circular holes and cracks under longitudinal shear are constructed. The analysis of cracks limit equilibrium using the end zone model is performed based on nonlocal fracture criterion with force condition of the crack tip advance and deformation condition for determination of the crack end zone face advance.
