. . "Suggested project deals with behaviour and propagation of a fatigue crack near and through bi-material interface. It makes wider and more general results from solution of project GA CR 106/01/0381 %22Propagation of a fatigue crack through the interface between two materials%22, where was solved this problem with assumption of ideal interface between two elastic materials. The project is aimed to consider more realistic interface model and more general behaviour of both materials (influence of anisotropy and plasticity of both materials). Presumptive results make it possible quantitative description of crack propagation rate for crack propagated through the material interface. The result makes it possible an estimation of residual fatigue life of composite bodies. Calculated threshold values for fatigue crack propagation with crack tip at the bi-material interface can for given conditions estimate whether the cracks will stop or will propagate to the second material.
