Abstract

In the present research a new hybrid multilevel approach was developed. It is shown that discrete-continual approach of excitable cellular automata can be successfully applied to simulation of deformation processes in systems with clearly pronounced interfaces. Explicit account of interfaces at various scales (interface between coating and substrate, grain boundaries etc.) allowed estimating power of stress concentrators to occur at these boundaries and also investigating specific features of stress field evolution in systems with coatings under dynamic compression by indenter.
