A finite element calculation of stress intensity factors by a modified crack closure integral
E.F. Rybicki,M. F. Kanninen +1 more
TL;DR: In this article, an efficient technique for evaluating stress intensity factors is presented, based on the crack closure integral, which can be used with a constant strain finite element stress analysis and a coarse grid.

Representation of singularities with isoparametric finite elements
TL;DR: In this paper, the development of a generalized quadrilateral finite element that includes a singular point at a corner node is presented, and the global-local concept of finite elements is used to formulate the complete set of equations.

The calculation of stress intensity factors for combined tensile and shear loading
T. K. Hellen,W. S. Blackburn +1 more
TL;DR: In this paper, stress intensity calculations are presented for cases of combined tensile and shear loading for a linear elastic material using functions of a complex variable, and a theory is developed to determine the direction of maximum energy release rate.

On the convergence of the finite element method for problems with singularity
Tong Pin,Theodore H. H. Pian +1 more
TL;DR: For problems with singularities, the convergence rate for the finite element method is often controlled by the nature of the solution near the points of singularity as discussed by the authors. And unless the singularities are properly handled, the regular so-called high-accuracy element will not be able to improve the rate of convergence.
