Conventional Coulomb model assumes constant friction coefficient in sheet metal forming simulation. It tends to predict too high friction shear stress in forming advanced high-strength steels (AHSS). Study is conducted by firstly designing an experiment method to develop a pressure-dependent variable friction model for DP780 AHSS sheet sliding against DC53 cold-work tool. The model is then used to simulate the forming and springback of U-shape bending under tension. Comparison of the predicted results with (i) pressure-dependent variable friction model, (ii) constant friction model, and the result of experimental verification indicates significant improvement of springback prediction with the proposed model.
