Abstract
The finite element method for the determination of weight functions in a two-dimensional mixed mode cracked body with finite dimension is presented. The generalized form of the crack-face weight functions for modes I and II are successfully demonstrated by using the least squares fitting procedure. Explicit weight functions are presented for plates of finite width and length containing edge and central cracks. The stress intensity factors KI and KII can be obtained for any arbitrary loading from the weight functions. Comparison of the calculated results with some solutions by other workers from the literature confirms the efficiency and accuracy of the weight function method. © 1990.
