Original Abstract

The usual approach in assessing the stability of general singular stress concentrators developed and presented in the first part of this contribution is applied to configurations corresponding to bi-material notches. Two stability criteria based on the knowledge of the tangential stress and the strain energy density factor distribution in the vicinity of the bi-material notch are formulated. The critical stress for crack initiation and the initial crack propagation direction are calculated as a function of the geometry and material properties of the bi-material notch.
