Abstract：

The uniaxial tensile test data of different strength steels were fit by simulation software AutoForm with the flow stress model applied in the current mainstream software CAE, and the selection principles of flow stress model for different strength steels during the simulation process were analyzed. Then, the simulation analysis results obtained by different yield criteria were compared with the actual experimental data, and the selection principles of yield criteria for different strength steels during the simulation process were summarized. The results show that for high-strength steel, the combined H-S hybrid model is selected as the flow stress model, and the simulated stress-strain curve is closer to the true stress-strain behavior. And for low-alloy high-strength steel and traditional soft steel such as IF steel, the simulation results are more consistent with the real situation by choosing BBC yield criteria and Hill48 yield criteria respectively. Thus, the research result has practical value for CAE simulation analysis of automobile stamping parts.
