Analysis of cracks in 3D piezoelectric media with various electrical boundary conditions
TL;DR: A weakly singular, symmetric Galerkin boundary element method capable of solving problems of isolated cracks in three-dimensional, linear anisotropic piezoelectric, infinite media with various types of crack-face boundary conditions including impermeable, permeable, semi-permeable and the energetically consistent boundary condition introduced by Landis (Int J Solids Struct 41:6291-6315, 2004) is established as mentioned in this paper.

Elliptical inclusion problem in antiplane piezoelectricity: Implications for fracture mechanics
TL;DR: In this paper, an elliptical piezoelectric inclusion embedded in an infinite lattice matrix is analyzed in the framework of linear PDE, and the energy release rate of a self-similarly expanding slender crack in the presence of electric fields is obtained by using the generalized M-integral.

Study on crack propagation in ferroelectric single crystal under electric loading
TL;DR: In this article, a fracture model based on energy analysis was developed which indicated that the energy variation due to the domain switching provided the thermodynamic driving force for the crack propagation under pure electric loading.
