Book Description
An analytical method is described for computing the nonlinear thermal and mechanical response of laminated plates. The material model focuses upon the behavior of metal matrix materials by relating the nonlinear composite response to plasticity effects in the matrix. The foundation of the analysis is the unidirectional material model which is used to compute the instantaneous properties of the lamina based upon the properties of the fibers and matrix. The unidirectional model assumes that the fibers properties are constant with temperature and assumes that the matrix can be modelled as a temperature dependent, bilinear, kinematically hardening material. An incremental approach is used to compute average stresses in the fibers and matrix caused by arbitrary mechanical and thermal loads. The layer model is incorporated in an incremental laminated plate theory to compute the nonlinear response of laminated metal matrix composites of general orientation and stacking sequence. The report includes comparisons of the method with other analytical approaches and compares theoretical calculations with measured experimental material behavior. A section is included which describes the limitations of the material model.

Book Description
An analytical, inelastic micromechanical model, with temperature-dependent matrix properties, is employed to study metal matrix composite (MMC) laminates subjected to thermomechanical loading. The predictions are based on knowledge of the thermomechanical response of transversely isotropic, elastic graphite or silicon carbide fibers and elastic-viscoplastic, work-hardening, temperature-dependent titanium or aluminum matrix. The model is applied to predict initial yielding and thermomechanical response of silicon carbide/titanium and graphite/aluminum laminates. The results demonstrate the effect of cooling from a stress-free temperature and the mismatch of thermal and mechanical properties of the constituent phases on the laminate's subsequent mechanical response. Typical results are presented for [±45], laminates subjected to monotonic tension, cyclic tension/compression, biaxial tension, and thermal loadings. It is shown that inclusion of temperature-dependent properties has a significant influence on both the initial yield surface and the inelastic response of metal matrix composites. It is also shown that the degree of applied biaxial loading has a significant effect on the response of laminates.
