. "\"An increasing exploitation of composite materials, protective surface layers, thermal barriers or functionally gradient materials requires to extend safety assessment approaches of the fracture mechanics, originally developed for isotropic homogeneous materials, to the field of anisotropic, strongly heterogeneous media. A typical situation is that of crack at the interface of anisotropic materials, like neighbouring plies in laminates, matrix/fibre or surface layer/substrate interfaces. The problem isfurther complicated due to crack face bridging by particles or fibres and non-linear material response in the wake of crack respectively. Recently, the technique of so-called two state interaction integrals has been increasingly applied to the evaluationof fracture mechanics parameters. A necessary condition for success of this approach is the existence of an \"\"auxiliary\"\" solution. The project will aim to develop an effective tool for the determination of (generalised) stress intensity factors as well as\""@en . . "2007-12-31+01:00"^^ . . .
