Effects of weld strength heterogeneity on crack driving force in stress and strain based design scenarios Ghent University
Weld strength mismatch is a key factor with respect to the assessment of a flawed girth weld. However, it is challenging to assign a single strength mismatch value to girth welds, which are generally heterogeneous in terms of constitutive behavior. The authors have recently developed a method ('homogenization') to account for weld strength property variations in the estimation of crack driving force response and the corresponding tensile limit ...
