Abstract

The effects of stress concentrations on stress intensity factors at plates under tensile load with welded-on flat side gussets have been studied. The correction function Yu of the crack configuration has been split into a function for the general configuration Y and a function for the local stress concentration Mk due to the weld and the gusset. The Mk values have been calculated by finite element analysis and by a simplified procedure based on the weight function approach. The results have been interpolated, giving a parametric formula for a wide range of variation in dimensions.
