Weight functions and stress intensity factors for corner quarter-elliptical crack in finite thickness plate subjected to in-plane loading
TL;DR: In this article, the authors derived approximate weight functions for the profile and frontal plane crack front points of a corner quarter-elliptical crack in finite thickness plate, subjected to mode I, in-plane loading, by using the method of universal weight functions by Shen and Glinka.

Fracture mechanics weight functions in three dimensions - Subtraction of fundamental fields
TL;DR: In this article, a new procedure is presented for the determination of the fracture mechanics weight functions that are required for the evaluation of stress intensity factors in cracked solids, which are proportional to the displacements on the boundary of the solid when the only loading is a pair of self-equilibrated point forces at the crack front.

Some remarks on elastic crack-tip stress fields
TL;DR: In this paper, it was shown that if the displacement field and stress intensity factor are known as functions of crack length for any symmetrical load system acting on a linear elastic body in plane strain, then the stress intensity factors for any other symmetric load system whatsoever on the same body may be directly determined.

The distribution of stress in the neighbourhood of a flat elliptical crack in an elastic solid
A. E. Green,I. N. Sneddon +1 more
TL;DR: In this paper, the authors considered the distribution of stress near a flat elliptical crack in a body of infinite extent under a uniform tension at infinity perpendicular to the plane of the crack, where the body at infinity is in a uniform state of stress whose principal axes are parallel to the axes of the cavity.

Application of the boundary-integral equation method to three dimensional stress analysis☆☆☆
TL;DR: The boundary integral equation (BE) method as mentioned in this paper is based on a mathematical formulation which reduces the dimensionality of a problem by relating surface tractions to surface displacements and finds the stresses at any point are then found by direct quadrature from the entirety of surface data.
