SINOPSIS

Propagation of a crack located on the interface of media in a piecewise homogenous structured material is considered. Under tension applied at infinity, the mode I fracture is realized. The case when elastic characteristics of materials coincide and strength ones differ greatly is analyzed in detail. The description of construction of diagrams for quasi-brittle fracture is given for a plane stressed state.
