Abstract : During this seven month project efforts continued on the development of advanced analytical and numerical techniques which can be effectively combined to provide advanced thermomechanical modeling of composite materials with nonlinear constituents. The areas of emphasis during this period were: development of thermoplastic and thermoviscoplastic models of composite materials using transformation strains; finite element formulation of bimodal plasticity model in combination with various forms of dimensional reduction; idealization control for composite materials.
