We consider the transient thermoelastic behavior of the functionally graded divertor plate due to a thermal shock with temperature-dependent properties. The development of a micromechanical model for the functionally graded materials is presented, and its application to thermoelastic analysis is discussed for the W-Cu functionally graded divertor plate of the International Thermonuclear Experimental Reactor. The divertor plate is made of a graded layer bonded between a homogeneous substrate and a homogeneous coating, and it is subjected to a cycle of heating and cooling on the coating surface of the material. The thermal and elastic properties of the material are dependent on the temperature and the position. Numerical results presented include the transient temperature distribution and the transient thermal stresses. |
