Abstract

Within the framework of a two-component medium, based on a phenomenological approach, a system of governing equations has been developed that describes the thermomechanical behavior of an elastomer highly filled with fine particles under conditions of a curing reaction (vulcanization) with adhesive contact conditions at the filler-matrix interface. The model is intended to describe the stress- strain state in the temperature range covering the intervals of phase and relaxation transitions at finite deformations. The basic equations of thermo-mechano-chemistry turn out to be related to the mutual influence of the stress-strain state of the curing elastomer and reaction kinetics. The results of numerical experiments are presented that demonstrate the possibility of describing the characteristic features of deformation processes characteristic of highly filled elastomers during curing
