• This paper presents dynamic failure mechanism of the spot weld nugget under the shear loading mode. The data collected from an impact experiment are presented. In addition, a finite element model with the bilinear hardening material model is established. The model responses agree well with experiment data for the cases with and without nugget crack. The study suggests that the yield strength of the nugget increases by four times of the base material due to the manufacturing process of the spot weld and due to the high strain rate loading.
