Mode III fracture analysis by Trefftz boundary element method

Cui, Yuhong; Wang, Juan; Qin, Qing Hua; Dhanasekar, Manicka


This paper presents a hybrid Trefftz (HT) boundary element method (BEM) by using two indirect techniques for mode III fracture problems. Two Trefftz complete functions of Laplace equation for normal elements and a special purpose Trefftz function for crack elements are proposed in deriving the Galerkin and the collocation techniques of HT BEM. Then two auxiliary functions are introduced to improve the accuracy of the displacement field near the crack tips, and stress intensity factor (SIF) is...[Show more]
