This review article focuses on two areas: the behaviour of aviation and rocket nose fairings made of radiotransparent ceramic materials of celsian composition; and the processing of superhard materials. Superior thermal stability and mechanical strength are the most important criteria when choosing materials subjected to high thermomechanical loads—as in aerospace and advanced materials processing. In both these areas, calculation methods for composite materials are based on discretized solutions of continuum mechanics equations. They can be found using finite element methods (FEM). An expert system was developed to assist in determining rational design parameters and optimal conditions for tool manufacture and use.
