## Abstract This paper presents a boundary element method (BEM) procedure for a linear elastic fracture mechanics analysis in twoβdimensional anisotropic bimaterials. In this formulation, a displacement integral equation is only collocated on the uncracked boundary, and a traction integral equation

A technique to evaluate the dynamic stress intensity factors and T-stress is developed by extending the scaled boundary finite-element method. Only the boundary of the problem domain is discretized. The inertial effect at high frequencies is modeled by a continued fraction solution of the dynamic st
The stress intensity factors for bimaterial interface cracks are determined by the boundary element method employing the multi-region technique and the double-point concept. A formula relating the stress intensity factors to the crack surface displacement, which is applicable to both the homogeneous
A~tract--The isoparametric finite elements are applied to determine the stress intensity factors for a pressurized crack perpendicular to and terminating at the interface of two bonded dissimilar materials. A proper definition for the stress intensity factors of a crack perpendicular to a bimaterial
In the present paper, a combination of the boundary element method is proposed for calculating the stress intensity factors of two-dimensional crack problems including mixed mode ones. In this method, finite elements are only allocated around a crack tip and boundary elements are used to discretize
+ract-A formula is derived for determining the stress intensity factors from the path independent J-integral which has been formulated in the previous paper as the energy release rate by taking the effect of inertia into account. Both pure and mixed mode problems of a suddenly loaded crack can be an
