Abstract
In this paper, we present a general two-dimensional finite element alternating method for the determination of weight functions for isotropic or orthotropic cracked structures, subjected to mixed-mode loading. The numerical results show that the weight functions are indeed load-independent, and are insensitive to a wide range of virtual crack extensions of Δa (10-3a ∼ 10-9a). The present alternating procedure (which involves a stress analysis of only the uncracked structure) is indeed a most effective technique for engineering fracture and life estimation analyses.
