Extended Finite Element Method for Dynamic Fracture of Piezo-Electric Materials (2012)

Nguyen-Vinh, H. ; Bakar, I. ; Msekh, Mohammed Abdulrazzak ; Song, Jeong-Hoon ; Muthu, Jacob ; Zi, Goangseup ; Le, P. ; Bordas, Stéphane Pierre Alain ; Simpson, R. ; Natarajan, S. ; Lahmer, Tom ; Rabczuk, Timon

We present an extended finite element formulation for dynamic fracture of piezo-electric materials. The method is developed in the context of linear elastic fracture mechanics. It is applied to mode I and mixed mode-fracture for quasi-steady cracks. An implicit time integration scheme is exploited. The results are compared to results obtained with the boundary element method and show excellent agreement.
