Modelling and simulation of coating-substrate-systems - state-of-the-art and future trends

Machining Technologies in the last years are focused on new workpiece materials, new environmental demands and higher productivity. That’s the driving force for the development of new coating-substrate-systems (CSS). The coating structure has been approximated by homogenous and isotropic material behaviour. That’s why continuum mechanicals methods (like conventional mechanics and conventional Finite Element methods) can be applied. For new higher effective coating-substrate- systems, like superlattice coatings, the application of conventionally methods tends to break down. The main goal of the paper is to provide a comprehensive review to the state-of-the-art in the modelling and simulation of coating-subs trate-systems and also to have a look into the future, based on the author’s research on a new physically, mathematically and mechanically based hybrid simulation technology.
