In conjunction with the quarter-point element, a wide range of stress intensity factor computation techniques may be employed. Of these, the displacement correlation technique (DCT) and the quarterpoint displacement technique (QPDT) have been in common use. It has been suggested by various investiga

This communication studies a procedure for stress intensity factor computations using traction singular quarter-point boundary elements. Opening mode stress intensity factors are computed from the tractions' nodal values at the crack tip. A comparison is made between the factors calculated using thi

## Abstract Finite element methods are used to calculate the stress intensity factors for three‐dimensional geometries containing a number of depths of crack subjected to various loads. Special elements are used at the tip to represent the variation of the displacement with respect to the square ro

In this paper an analytical solution is developed for two three-dimensional coplanar rectanguiar-shaped cracks embedded in an infinite elastic medium and subiected to normal loading. Employing two-dimensional integral transforms, the solution of the problem is reduced to triple integral equations. A

The main content of this paper is: (1) To present a proof of singularity with an arbitrary triangular element rather than an isosceles triangular element as R. S. Barsoum did. (2) To present three numerical examples for the determination of stress intensity factors by using this kind of element fo
