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.

Effect of Porosity Shape, Size and Distribution on Stress Intensity Factors in Spot Welded Joints: A Finite Element Study

“…The behavior of fractures started in the steel matrix and exposed to tensile stresses was examined using the ABAQUS computer code [6], which is based on the finite element approach. Our earlier work [15][16][17] had successfully used the finite element model, and more recent calculations [4,18,19] employing this model's mesh size convergence have validated this. Here, the key elements of the technique are explained.…”
