A parallel finite element analysis based on a domain decomposition method (DDM) is considered for the analysis of thermal and mechanical coupling behavior. In the present DDM, an analysis domain is divided into a number of smaller subdomains without cverlap. The mechanical responce analysis for the subdomain is performed under the constraint of displacement and traction force as is developed by Yagawa et al., while heat transfer analysis is carried out under the constraint of temperature and heat flux in the present paper. The constraint is satisfied through iterative calculation algorithm based on the conjugate gradient method. The characteristics of domain decomposition method implemented on a parallel computer consisted of PC cluster is studied by the transient thermal stress analysis in a nozzle of FBR.
