Analysis of the Analytical and Numerical Studies for Crack Widening in Lamellar Metal-Ceramic Composites

Abstract

Metal-ceramic composites offer many advantages over monolithic metals and their alloys such as high specific stiffness, strength and good thermal properties. In this paper, stress fields in a single-domain sample of metal-ceramic composite containing multiple cracks in the ceramic layer are investigated. In our previous studies the cracked microstructure for different stage of damage is modeled by analytical and computational approaches. In this paper the assumptions of the analytical model were verified using FE-models for different crack widening.
