In the paper, a new kind of stress singular element is introduced for crack problems. This kind of element is more simple and widely used than those presented before. In the paper, a cube with embedded circular crack and a first kind Benchmark problem are studied. The study shows that using quarter-

β¦ Synopsis
A new 3 node singular finite element has been derived. This element is incompatible and has to be used in conjunction with incompatible 4 node quadrilateral elements. An extension to three dimensional problems is also presented. This element is used to compute the stress intensity factor along the crack border in a wire with a semi elliptical surface crack subject to tension and for a large variety of elliptical shapes.

In the paper, an ~vestigation into the stress intensity factors of mixed-mode three dimensional crack problem is studied. In the method presented in the paper, the number of elements and nodes can be decreased greatly while computational accuracy and efficiency increase, the continuous functions of
In this paper we consider the problem of determining the distribution of stress in the neighbourhood of a crack in an infinitely long strip bonded to semi-infinite elastic planes on either side. By the use of Fourier transforms we reduce the problem to solving a single Fredholm integral equation of
## Abstract In this work a fast solver for largeβscale threeβdimensional elastodynamic crack problems is presented, implemented, and tested. The dual boundary element method in the Laplace transform domain is used for the accurate dynamic analysis of cracked bodies. The fast solution procedure is b
