Although the complexity of the frictional behaviour is identified as a key factor for the prediction accuracy, the industry commonly considers a constant friction coefficient for the whole tool. Furthermore, the influence of roughness distribution of the tool in the friction behaviour has not yet been addressed. In this study the influence of the die local roughness in an advanced friction model has been evaluated in three industrial automotive components. The newly implemented advanced friction model (TriboZone) is suggested for advance or mature process verifications. 0301-679X https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=164582 https://hdl.handle.net/20.500.11984/5372 Surface topography Sliding forming Friction Numerical study of advanced friction modelling for sheet metal forming: influence of the die local roughness
