Abstract We study the influence of plastic anisotropy on the predictions of some engineering models of fracture mechanics. We consider a welded specimen with a crack in the weld joint under tensile loads. The weld joint material and the main material are assumed to obey the orthotropic yield condition. A comparison with the isotropic cases shows that the limit load significantly depends on the plastic anisotropy parameters of the materials. Since this load is one of the basic input parameters of engineering models of fracture mechanics, the plastic anisotropy parameters must strongly affect the predictions of such models, and these should be taken into account in the structural analysis.
Keywords plastic anisotropy, fracture, weld joints, engineering approaches
