MIXING ANISOTROPIC FORMULATION FOR ANALYSIS OF COMPOSITES

A general constitutive model adequate for analysis of the thermomechan ical response of composite materials is presented. The model is based on the mixture of the basic substances of the composite and allows the evaluation of the interdependence between the constitutive behaviour of different compounding materials. The behaviour of the each compound is modelled by a general anisotropic thermo-elasto-plastic model, ter med the 'base model'. The different base models for each compound are combined using mixing theory to simulate the behaviour of the multipha se material.
