Modeling of Shock Wave Resistance in Composite Solids

AbstractThe paper describes briefly the problem of elastic-plastic shock wave propagation in solids. Such waves originate by acting of explosion waves or by high velocity impact of solid parts on the structure. Computational simulations are applied to the elastic problem of propagation of waves in composite material reinforced by fibres. The fibres are supposed to be much stiffer than the matrix. The wave in such material is influenced by reflexion and refraction on the interface between fibres and the matrix and by the interaction of then waves. The wave is strongly damped in such composites in this way. The aim of this paper is to contribute better understanding and modelling of waves propagation using commercial software ABAQUS
