Residual stress fields in functionally graded material rotating disc under thermo-mechanical loading is obtained by using the variable material properties method. The mixture model of Tamura–Tomato–Ozawa is used to correlate the overall mechanical behavior to the behavior of the constitutive phases in the construction of a rotating disc. The elastic-linearly kinematic hardening plastic material model is used for the metallic phase and a linear perfectly elastic behavior is assumed for the ceramic part. A finite element method analysis by using ABAQUS software is performed to assess the validity of the proposed method. The effect of velocity and temperature on the residual stress fields are studied. A study also worked out to see the effect of different parameters upon the residual stress fields. The effect of reverse yielding on the transposition of the compressive residual stress zone is investigated.
