This paper is concerned with the failure characteristics and the failure load of spot welds of AHSS under combined axial and shear loading conditions. A testing fixture and a specimen are newly designed to impose the pure-shear load acting on a spot weld. The testing fixture and the specimen proposed by Song et al. are used to impose the combined axial and shear load at the loading angle from 0° to 75° on a spot weld. Using those testing fixtures and specimens, failure tests of the spot weld of TRIP590 1.2t, DP780 1.0t, and DP980 1.2t are conducted with seven different conditions of combined loading. Based on the experimental results, failure loads and failure behaviors of a spot weld of AHSS are investigated with respect to the different loading angles. Failure loads of the spot weld obtained from failure tests are interpolated to construct the Song and Huh’s failure model , which facilitates the failure description of a spot weld in the macroscopic finite element analysis of auto-body crashworthiness.
