MICROMECHANICS OF THE PROCESS INDUCED DAMAGE EVOLUTION IN THERMOSETS

摘要

The present study focuses on the formulation of a micromechanically based analytical model of the evolution of damage in thermoset resins during cure. The study emphasizes the effect of the microstructural disorder on the macro response. To avoid introduction of arbitrary fitting constants and parameters the problem is considered on three different length scales. The proposed model consists of a system of equations governing the exothermic chemical reaction, heat transfer and deformation. Effective properties of the solid and distribution of stresses are determined using non-traditional micromechanical models. [References: 46]
