Abstract:
The research is conducted in response to the need for microstructural-based theories which furnish increased simulation capabilities of metal-matrix composite structures in both static and dynamic regimes with a minimum of model parameters to be experimentally determined. The objective of the research is to develop a nonlinear model of binary metal-matrix composites that will provide greater accuracy than existing models in linear and nonlinear regimes for static and dynamic loading. Furthermore, in an effort to accommodate practical structural configurations a plate theory is developed for fiber-reinforced composite plates. The progress made during the first years effort toward achieving the above objectives includes 1 the development and validation of a linear mixture model which accounts for effective moduli and harmonic wave dispersion, 2 testing of methodologies for including nonlinear material responses, and 3 a significant improvement of existing laminated composite theories to account for inelastic responses driven by in-plane strains.
