| Abstract: | In this paper, a method for extracting stress intensity factors (SIFs) in orthotropic
thermoelasticity fracture by the extended finite element method (XFEM) and
interaction integral method is presented. The proposed method is utilized in linear elastic
crack problems. The numerical results of the SIFs are presented and compared with
those obtained using boundary element method (BEM). The good accordance among
these two methods proves the applicability of the proposed approach and conforms its
capability of efficiently extracting thermoelasticity fracture parameters in orthotropic
material. |
