What is it about?
The crack at the weld nugget was simulated using Franc2D. The crack path and propagation have been simulated. Hence, the comparison with experiments has been presented. The stress intensity factor was calculated from Franc2D. A fracture mechanics approach has been used in this simulation.

Why is it important?
Using the 2D FE simulator Franc2D to show the crack propagation. The crack paths simulation and fracture predictions are presented for a single sheet spot welding. The stress intensity factor (SIF) has been calculated using Fracture Analysis Code (Franc2D). The crack path model has been validated. The accurate SIF solutions and crack path simulation have been shown.
Perspectives
The determination of crack initiation and propagation paths will determine the fatigue life and structural integrity of the spot weld joints.
