N2 - The initiation of a transverse shear edge crack in elastoplastic materials with the limiting strain is considered. The crack propagation criterion is formulated using a modified Leonov - Panasyuk - Dugdale model using the additional parameter - the width of the plasticity zone. The coupled fracture criterion for quasi-brittle fracture is formulated for mode II cracks in an elastoplastic material in the vicinity of the crack tip. The sequential analysis of the possibility of applying the proposed fracture criterion in determining the critical loads for solids containing edge cracks of transverse shear at the interface of different media is performed. Quasi-brittle fracture diagrams are constructed for a composite plate with an edge crack under plane strain and plane stress conditions. The critical loads were found numerically for the quasi-ductile and ductile fracture types.
