Fracture mechanisms of Al/steel resistance spot welds in lap shear test
TL;DR: In this paper, failure modes, mechanical strength and fracture mechanism of Al/steel resistance spot welds in lap shear test were investigated, and three major fracture mechanisms and failure modes were identified: semi-brittle or brittle fracture in the intermetallic compound (IMC) layer which led to interfacial failure, ductile fracture in aluminum fusion zone (FZ), and ductile fractures in the aluminum heat affected zone (HAZ) which lead to the engineering preferred button pullout failure.
