Microdynamics: continuum modelling the simple composite materials

In this paper there is analyzed a certain general modelling procedure for the investigation of non-stationary processes in periodic composites. The resulting macro-models take into account the effect of the micro-structure length dimension on the dynamic behaviour of the body and are simple enough to be applied to the analysis of engineering problems. The modelling procedure under consideration was recently applied in a series of papers to some selected composite materials and structures. The aim of this study is to generalize the obtained partial results and to formulate the above macro-models within a framework of the nonlinear continuum mechanics for an arbitrary simple material.
