Finite element analysis of the interface defect in ceramic-metal assemblies: Alumina-Silver

Abstract

In the present work, the finite element analysis was employed to study the distribution of mechanical stress generated in metal-ceramic bimaterial. A micromechanical model is proposed to explain a phenomenon of defect observed in the metal-ceramic interface. The distribution of this stress in the ceramic around this defect was the subject of a numerical analysis using the finite element method. The analysis has been extended to the effect of defect-defect interaction, defect size and form.
