Abstract
The non-classical problems of the fracture of materials loaded along the cracks they contain are analyzed. Two fracture mechanisms are considered, namely, the fracture of materials with initial (residual) stresses acting in parallel to the surfaces of cracks location and the fracture of the bodies compressed along cracks. In the study of such problems, a new combined approach developed in the framework of the three-dimensional linearized mechanics of deformable bodies is used. The results of the investigation of two- and three-dimensional problems for typical configurations of parallel coaxial Mode I and Mode II cracks are presented. The effect of residual stresses on stress intensity factors is analyzed for highly elastic materials and composites. The compressive strength for bodies with interacting cracks located in parallel planes under compression is calculated using the approach mentioned. The crack length (diameter), mechanical properties of materials and the mutual position of cracks were found to influence the critical fracture parameters.
