Abstract [en]

Friction is an important parameter to control in sheet metal forming since it influences the flow of material in the process. Consequently, it is also an important parameter in the design process of new stamping dies when numerical simulations are utilized. Today, the most commonly used friction model in forming simulations is CoulombĀ“s friction which is a strong simplification of the tribological system. In this work an advanced friction model is developed, which considers properties of tool and sheet surface topography (spatial and height), lubricant, sheet material, and process parameters such as sliding speed and contact pressure. The results show that the model can predict the frictional behavior over a wide range of influencing parameters. A regression analysis of model and experimental results, Bending-Under-Tension friction test, shows acorrelation of R2=0.89.
