This paper presents a study on the application of the weight function and finite element methods to evaluate residual stress intensity factors in welded test samples. Three specimen geometries and various residual stress profiles were studied. Comparisons of the two different methods were made in te

A numerical technique for simple and efficient integration of weight functions is presented. The method enables the stress intensity factors to be calculated with the aid of a hand calculator for any non-linear stress distribution normal to the crack surfaces. The proposed integration routine is val
## At&r&-A finite element method with virtual crack extension technique is employed to find the weight function of the stress intensity factor for a cracked composite laminate. Since the weight function is load independent, once it is obtained, the stress intensity factor of a cracked laminate sub
+ract-A formula is derived for determining the stress intensity factors from the path independent J-integral which has been formulated in the previous paper as the energy release rate by taking the effect of inertia into account. Both pure and mixed mode problems of a suddenly loaded crack can be an
The calculation of stress intensity factors for complicated crack configurations in finite plates usually presents substantial difficulty. A version of the finite element method solves such problems approximately by means of special cracked elements. A general procedure for evaluating the stiffness
## Abstract Finite element methods are used to calculate the stress intensity factors for threeβdimensional 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
