A personal computer program of three-dimensional thermal stress analysis for anisotropic materials like composites has been developed in this paper. As an example, the deformations of bi-metal and angle-ply laminates under thermal conditions have been analyzed. From the computational results, the torsional phenomenon, which is caused by the coupling and the effect of free edge on stress, has been recognized. When the residual stress is taken into consideration, the tensile strength of angle-ply

As a result, it is shown that the fracture pattern can be changed by property of matrix. From these results, it can be recognized that the developed computer program is very useful for the analysis of mechanical behaviors of composites under thermal condition.
