Abstract:
This report presents the work performed under ONR contract number N00014-85-K-0733 during the period 1985-1990. The main objective of the project was to develop a computational facility for inelastic analysis of fibrous composite materials based on micromechanics. The theoretical work focused on development of micromechanical models for thermoplastic and thermoviscoplastic fibrous composites based on experimental observations of certain phenomena found in unreinforced and fiber reinforced metals. Implementation of the material models in computational procedures for analysis of composite materials and structures was an important part of the research. Accomplishments in these areas and in development of a layer-wise composite shell element, also performed under this contract, are described.
