Abstract
In the current paper, a numerical investigation based on the finite element method was constructed to analyse fracture mechanics of two L-shaped sheets welded with resistance welding. The fracture behaviour of the welded structure is considered with the assumption of a crack at the interface of the welded sheets. The study was treated as a linear elastic fracture mechanics problem in mixed mode, under plane stress conditions. Computations were performed using the commercial FE software package ABAQUS. The modelling results highlight the dependence of the stress intensity factors on key design parameters of spot welds such as nugget diameter, bent curvatures, sheet thickness, material properties and the applied load.
