Evaluation of Intensities of Singularity Along a Singular Line Near the Vertex in 3D Piezoelectric Bonded Joint Using a Conservative Integral

Abstract

Singular stress fields in three-dimensional piezoelectric bonded joints with multi-terms of singularities are investigated. The conservative integral formulation is developed for calculating the intensity of singularity at a point located on the singular line (along a free edge). The intensities of singularities at several positions along the singular line of the interface are examined.
