Abstract

The paper deals with an elastomer body having a random 3D-distribution of ellipsoidal mutually parallel voids. By making use of Levin’s formulae effective stiffness as well as thermal expansion tensors are found numerically. Slight disorder case differs unsignificantly from parallel voids. For such a disorder these effective material features are found. Subsequently, the energy release rate is used as a triggering tool for opening and closing of existing cracks. The accomplished results make possible a further application to kinetic equations.

Keywords: elastomer, void, damage, material constants, effective continuum
