A general boundary element analysis of 2-D linear elastic fracture mechanics
TL;DR: In this article, a boundary element method (BEM) analysis of linear elastic fracture mechanics in two-dimensional solids is presented, which is an extension of the work by Pan and Amadei (1996a) and is such that the displacement and traction integral equations are collocated on the no-crack boundary and on one side of the crack surface.

Fracture mechanics analysis of cracked 2-D anisotropic media with a new formulation of the boundary element method
Ernian Pan,Bernard Amadei +1 more
TL;DR: In this paper, a new formulation of the boundary element method (BEM) is proposed to calculate stress intensity factors for cracked 2-D anisotropic materials, and the most outstanding feature of this new approach is that the displacement and traction integral equations are collocated on the outside boundary of the problem (no-crack boundary) only and on one side of the crack surfaces only.

On cracks in rectilinearly anisotropic bodies
TL;DR: In this paper, the general equations for crack-tip stress fields in anisotropic bodies are derived making use of a complex variable approach and stress intensity factors, which permit concise representation of the conditions for crack extension, are defined and evaluated directly from stress functions.

A modified mapping-collocation technique for accurate calculation of stress intensity factors
Oscar L. Bowie,Donald M. Neal +1 more
TL;DR: In this paper, a technique combining the advantages of conformal mapping and boundary collocation arguments for calculating stress intensity factors for cracks in plane problems is described, which is applied to the problem of a circular disk with an internal crack under a loading of external hydrostatic tension.
