Abstract

A elastic-plastic analysis of AlN/Cu jointing plate was performed by FEM to study the residual stress produced in the jointing-cooling process. This residual stress due to the difference of thermal expansion coefficient between ceramics and metal was analyzed, considering the presence of initial defects in ceramics. A static fatigue life was estimated based on a stress intensity factor of the supper-posed stress of the residual stress and the bending stress in ceramics of AlN/Cu jointing plate with the various thickness of Al2O3 layer.
