Shielding of a crack tip by its nearby dislocations in cubic piezoelectric crystals
TL;DR: In this paper, an exact and closed-form solution for screw dislocation near a semi-infinite crack in cubic piezoelectric crystals was obtained explicitly in terms of two complex functions which contain three major sources: (a) the electromechanical field associated with the isolated dislocation, (b) the attendant fields generated by the image singularities of the dislocations, and (c) the interaction between the crack and the dislocation.

On the solution technique for the interior electric displacement in a piezoelectric crack with the semi-permeable electric condition
Guixi Li,Y. P. Wan,Z. zhong +2 more
TL;DR: In this paper , the authors proposed a semi-permeable crack condition to solve the crack interior electric displacement problem, where the electrical saturation zone-length is determined only by electrical load.
Fracture Behaviour of Cracked Functionally Graded Piezoelectric Materials (FGPMs)
TL;DR: In this article, the concept of functionally graded piezoelectric materials (FGPMs) has been introduced to improve the lifetime and reliability of traditional FGMs in reducing residual and thermal stresses.

Electro-mechanical crack systems: bound theorems, dual finite elements and error estimation
TL;DR: In this paper, the path independent integral I, which is the dual of the J-integral, for electro-mechanical coupling crack systems, is presented, and related bound theorems are established for J and I.

Green's Function of Cracks in Piezoelectric Material
TL;DR: In this paper, a general form solution for a piezoelectric material containing impermeable cracks subjected to a combined mechanical and in-plane electrical loading is considered based upon the Hilbert problem formulation.
