Thermoinelasticity of Damaged Elastomers by Self-consistent Method
Abstract
This study deals with an elastomer body having a random 3D distribution of two types of inclusions: spheroidal mutually parallel voids and differently oriented reinforcing parallel elastomeric stiff spheroidal short fibers. By the effective field approach, the effective stiffness four-tensor as well as the effective thermal expansion two-tensor are formulated and found numerically. Simultaneous and sequential embeddings of inclusions are compared. Damage evolution is described by a modified Vakulenko's approach, the endochronic thermodynamics. A brief account of the problem of effective elastic and thermal symmetry is taken. The results of the theory are applied to creep of an elastomeric PU-based composite caused by triangular history of compressive stress.
