Abstract
A numerical procedure for analyzing the temperature distribution in a hollow axisymmetric cylinder, made of functionally gradient material (FGM), was investigated. Based on the thermal elasticity theory and the arbitrary difference precise integration (ADPI) method, temperature distribution through the FGM cylinder in the ring section under a transient-state temperature field was developed and presented. A genetic algorithm (GA) was applied to the thermal stress optimal design of an FGM hollow cylinder, and as a result, the minimum thermal stress distribution in the FGM cylinder was obtained. A corresponding numerical procedure regarding to a ceramic-metal FGM cylinder was performed, and the computational results were discussed.
