Nonlinear analysis of a crack in 2D piezoelectric semiconductors with exact electric boundary conditions
TL;DR: In this article, a double iteration method was proposed to analyze a crack problem in a two-dimensional piezoelectric semiconductor, taking the exact electric boundary conditions into account.
Solución numérica para fractura en sólidos piezoeléctricos tridimensionales
TL;DR: In this paper, a mixed boundary element formulation for the analysis of 3D crack problems in transversely isotropic piezoelectric solids is presented, where displacement expressions of the fundamental solution obtained by Dunn and Wienecke, have been differentiated in order to obtain the traction terms and kernels for the hypersingular formulation.

An extended model for electrostatic tractions at crack faces in piezoelectrics
Andreas Ricoeur,Roman Gellmann +1 more
TL;DR: In this article, an extended model of fracture mechanics of piezoelectrics has been presented, which includes electrostatically-induced mechanical tractions in crack models yielding a significant crack closure effect, and it is predicted that the Mode-I======stress intensity factor is influenced by both a collinear normal stress parallel to the crack faces and a Mode-II====== shear loading.

A Permeable Wedge Crack in a Piezoelectric Material Under Antiplane Deformation
Sung Ryul Choi,Jai Hak Park +1 more
TL;DR: In this article, the authors analyze the problem of wedge cracks, which are geometrically unsymmetrical in transversely piezoelectric materials, and derive the Wiener-Hopf equation in a closed form, where the intensity factors of the stress and the electric displacement are obtained for any crack length as well as inclined and wedge angles.
