A fully parametric weight function (WF) is proposed for determining the stress intensity factors (SIFs) of an inclined edge crack carrying a terminal kink. The WF can evaluate with accuracy better than 0.4% the SIFs for cracks with initial inclination angle in the range [60°,60°], kinking angle in the range [90°,90°], and the ratio of kinked-to-initial-crack- length in the range [0,1/4]. For inclined straight edge cracks, the WF accuracy is better than that of WFs derived so far. The online version of the paper is provided with a MATLABÒ script containing functions that return the WF components and the SIFs.

Abstract

A fully parametric weight function (WF) is proposed for determining the stress intensity factors (SIFs) of an inclined edge crack carrying a terminal kink. The WF can evaluate with accuracy better than 0.4% the SIFs for cracks with initial inclination angle in the range [60°,60°], kinking angle in the range [90°,90°], and the ratio of kinked-to-initial-crack- length in the range [0,1/4]. For inclined straight edge cracks, the WF accuracy is better than that of WFs derived so far. The online version of the paper is provided with a MATLABÒ script containing functions that return the WF components and the SIFs.
