Summary:This article is intended as an investigation on material composition in functionally graded materials (FGMs) that enable to achieve two purposes simultaneously, securement of strength against thermal stress and improvement of heat resistance against thermal load, from the standpoint of multipurpose optimization. Application of genetic algorithm technique is investigated to find the set of the Pareto-optimal solutions in the multipurpose optimization problem of material composition in FGM. In this study, a multipurpose optimization problem of material composition is illustrated for a functionally graded circular plate. Assuming that zirconia/titanium alloy type of functionally graded circular plate is subjected to uniform heat supply from upper surface, we investigate how much two purposes, securement of strength and improvement of heat resistance, are achieved simultaneously by numerical calculation.
