Original Abstract
The work deals with a calculation of the fracture-mechanics parameters, which characterizes the stress field in the vicinicity of the crack tip terminating at the interface of two different orthotropic materials. The two main parameters - Generalized Stress Intensity Factor and T-stress in the Williams asymptotic expansion are discussed . For their computation, the two state "psi"-integral method and Continuously Distributed Dislocations technique are used. There will be also discussed possible approach how to formulate the fracture criterion for the cracks positioned very close to a bi-material interface or laying on it. Possibility of crack deflection along the interface and the propagation from the surface layer into the basic material will be taken into consideration.
