Thepressure dependent friction model of each material wasfitted to the experimental data obtained by StripDrawing tests and then implemented in the numerical simulation of an industrial automotive partdrawing process. The results showed important differences between defining a pressure dependent or aconstant friction coefficient. Finally, the experimental part was produced to compare the real geometrywith the predictions obtained with the different simulation strategies. An improvement of 20–25% inspringback prediction was achieved when using the pressure dependent friction model. eng &2016 Elsevier Ltd.
