Abstract

Interaction of arbitrarily located system of rectilinear bridged cracks is considered. It is assumed that the mixed boundary conditions are given on the boundary of the circular disk. It is accepted that the fracture zone is a finite length layer containing a material with partially disturbed bonds between its separate structural elements (end zone). Existence of bonds between the cracks surfaces in the end zones is simulated by application of cohesive forces caused by the presence of bonds to the crack surfaces. Limit equilibrium analysis of cracks is formulated, taking account the criterion of the limit traction of the bonds in the material at the edge of the cracks end zone.
