A conservative integral for calculating intensities of singularities at a 3D Piezoelectric bonded joint

(In case of three-real singularities)

Abstract

The conservative integral formulation is developed for calculating the intensities of singularities at a vertex of an interface in three-dimensional piezoelectric bonded joint. The model with three-real singularities is considered. The intensities of singularities of each term of stress singularity are calculated. Various integral areas, which located at various distances from the singular point, are used to investigate an influence of an integral area on an accuracy of results.
