Numerical simulation of sheet metal forming processes has become indispensable in the last decades. Although the complexity of the frictional behaviour is identified as a key factor for the prediction accuracy, the industry ...

The increasing demands for lightweight design in the transport industry have led to an extensive use of lightweight materials such as aluminium alloys. The forming of aluminium sheets however presents significant challenges ...

The aim of this work is to show the influence of defining a pressure dependent friction coefficient onnumerical springback predictions of a DX54D mild steel, a HSLA380 and a DP780 high strength steel. Thepressure dependent ...
