Micromechanics of Inelastic Composite Materials

Abstract

Under these circumstances, it fs essential to develop micromechanical theories which evaluate the local fields and predict the overall response under combined thermal and mechanical loads. The basic elements of these theories are geometrical modeling of the microstructures and local interactions, and constitutive modeling of the homogeneous phases. An essential requirement of the latter is to include inelastic deformation to model composite systems which exhibit nonlinear response under thermal and mechanical service loads. Since the early 1960s, micromechanics of composite materials has attracted many researchers. This led to significant theoretical developments for prediction of elastic and inelastic constitutive response, and motivated experimental validation. The purpose is to summarize these developments, and illustrate their application in predicting the overall response under thermomechanical loads. Although treatment of the subject in this chapter covers two-phase particulate and fibrous materials, the focus in applications will be on fibrous composites and laminates.
