Abstract :
The thermo-elasto-plastic behavior of a compositionally graded metal–ceramic structure is investigated under a homogeneous temperature load. The overall curvature change as well as the local stress and strain fields are predicted by a hierarchical finite element-mean field approach. The onset of failure with respect to various damage modes is discussed. The results are compared to other numerical predictions and to experiments.
