Abstract

The current paper presents finite element evaluations of brittle fracture parameters for subinterface and interface cracks in composite materials. It consists of two basic parts: in the first part the description of virtual crack closure integral methods is given and the finite element realization of this method is also presented. Second part of the work deals with the numerical analysis of different interfacial and non-interfacial cracks in heterogeneous media. The discussion of the obtained results is performed and the conclusions are drawn.
