N2 - This paper is concerned with the evaluation of the overall temperature-dependent elastic, thermal, and thermo-elastic material properties of metal-ceramic composites for high temperature applications. Effective properties of an aluminum/zirconia composite are obtained using micromechanics models and finite element analysis of representative volume elements (RVEs). RVE microstructures consisting of mono-sized spherical reinforcement particles embedded in a unit cube matrix were generated using a random sequential adsorption algorithm and event driven molecular dynamics simulation. The adopted algorithm allowed generating microstructures with high volume fractions of reinforcement particles up to 61%. Finite element analysis was performed to determine effective properties of the composite over a wide temperature range. The obtained computational results for effective elastic, thermal, and thermal expansion properties are consistent with the known analytical bounds.
