What is Failure Mechanism of Spot Welds in Steel about?

This paper investigates the failure mechanism of resistance spot welds in dual-phase steel lap-shear specimens through experimental observations and finite element analyses. The study finds that necking failure initiates near the middle of the nugget circumference and propagates along the nugget circumference, with analytical and computational results supporting these observations. The research provides insights into stress and strain distributions near the nugget, enhancing the understanding of spot weld f
