000001719 520__ $$2eng$$aThe contribution discusses possible approach for the formulation of fracture criteria for the general stress concentrators – especially a surface crack terminating at the interface of two dissimilar orthotropic media. The classical differential analysis is unsuitable due to the discontinuity in the elastic properties which leads on the interface to a zero or infinite energy release rates. Theory of the Finite Fracture Mechanic is used to overcome this problem (crack increase of finite length is used instead of the infinitesimal one). The three possibilities of the crack propagation are taken into the consideration – crack deflection (single or double) and a penetration of the crack across the interface into the substrate. The so-called matched asymptotic procedure in combination with FEM is used for the calculation of appropriate changes of potential energy caused by the fracture.
