Micromechanical modelling of functionally graded W-Cu materials for divertor plate compojnents in a fusion reacgtor

摘要

Themonuclear fusion process implementation has many materials problems and one of them is related to removal of impurities from plasma. In the International Thermonuculear Experimental Reactor (ITER), a divertor coneept has been incorporated for this purpose. In this work, the development of a micromechanical model for FGM is presented and its application to thermal-elasto -plastic analysis is discussed for the case of W-Cu FGM for ITER divertor plates.
