The one-dimensional calculation of thermally induced residual stresses, generated by fabrication of functionally graded materials (FGMs), is presented. In this study, a laminated plate theory is used to analyze the residual and thermal stresses in the FGM plates fabricated by a multilayered technique. The analytical results indicate that the residual stress distributions can be controlled by adjusting the compositional gradient across the thickness of the FGM plates and that the characteristics of thermal residual stress are more strongly dependent on the thermal expansion coefficients mismatch between ceramic and metal and the volume fraction of metal, in comparison with the mismatch of Young's moduli.
