1103 A conservative integral for calculating the intensity of singularity at 3D interface between piezoelectric and isotropic materials

Abstract

In the present study, the conservative integral formulation is developed for calculating the intensity of singularity at a vertex of the interface in three-dimensional transversely isotropic piezoelectric and isotropic material joints. External mechanical load is applied to the joints. In order to investigate the influence of integral area on the accuracy of the results, models with various integral areas are used. Finally, the distribution of stresses and electric displacements are compared with the FEM results.
