The Ceramic/metal gradient thermal barrier Coating Design Software (CCDS) is developed for analyzing the heat transfer and the thermal stress in the coatings, and for designing the optimal coating schemes. The CCDS is developed according to software engineering methodology with Borland C builder 5.0 and has user friendly interface. it is composed of three functional modules preproccss module and post process module.initial data are input in the preproccss module, calculation of the temperature and thermal stress is carried out in the analysis module, and visualizatin is realized by the post proccss module. Calculation is carried out by analytical method. tinite difference method and finite element method. In addition, the CCDS is enhanced by attaching an optimization design module which completes optinization design for eeramic/metal gradient thernal barrier coatings by ANSYS Parameter Design language (APDL) or genetic algorithm. and an expert system module which may propose schemes and suggestions for coating design The CCDS is useful for the design of ceramic/metal gradient thenual battier coating.
