Elasto-Plastic Damage Analysis of Functionally Graded Materials Subjected to Thermal Shock and Thermal Cycle
Author(s): Jae-Myung LEE and Yutaka TOI
Abstract :
The elasto-plastic damage behaviors of functionally graded materials (FGM) subjected to thermal loading are analyzed by the finite element method using continuum damage mechanics. Lemaitre's damage model is employed to analyze the damage behavior of a FGM disk subjected to thermal shock and a FGM coating subjected to thermal cycle. The effect of FGM on the thermal damage is discussed through some numerical examples for industrial materials. Numerical results reveal the validity of the present method for the development and the evaluation of new FGMs.
