| Abstract: | Focusing on the spot-welded structures of vehicles, the FE discrete model and mechanics model for spot-welded structures are established. The distribution of the stress and strain, and the corresponding correlations between stress, strain and structure and load of a spot-welded sample for tension and shear testing under different loads are simulated and analyzed with good results obtained. |
