Abstract
Stress singularity frequently occurs at a vertex in an interface of joints due to a discontinuity of materials. The stress singularity fields are one of the main factors responsible for debonding under mechanical or thermal loading. The stress distribution near the vertex in the interface of joints is very important to maintain the reliability of joints. However, the intensity of singularity for 3D transversely isotropic piezoelectric bi-material joints has not been made clear until now. In this paper, intensity of singularity in transversely isotropic piezoelectric dissimilar material joints is analyzed. The stress and electric displacement distributions on an interface and the intensity of singularity at the vertex are investigated using BEM.
