AbstractIt is proposed to develop and validate fast and robust algorithms and computer codes to simulate the processing of ceramic matrix composites. While the processing and parameters that control the efficient manufacturing of ceramic matrix composites can be studied experimentally, a validated mathematical model that accounts for the microstructural and processing parameters is a very economical and useful tool. The porposed interdisciplinary study should lead to a better understanding and design of optimum and economical processes for ceramic and glass matrix composites. The primary thrust would be to formulate a viscoelastic mathematical model for a ceramic matrix undergoing pressureless or pressure assisted densification. A robust and efficient non-linear finite element code will be developed to solve for full field variables such as density, stress and damage. Simple geometries such as particulate, whisker and unidirectional composites will be considered during the Phase I while laminated angle-ply, cross-ply and microcomposites will be considered during Phase II. Systematic sintering experiments selected ceramic composite systems with controlled conditions will also be conducted to validate the model.
