Numerical study of advanced friction modelling for sheet metal forming: influence of the die local roughness Zabala, Alaitz Sáenz de Argandoña, Eneko Llavori, Inigo Otegi, Nagore Mendiguren, Joseba Cañizares, Daniel Surface topography Sliding forming Friction 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 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. 2021-09-08T07:15:12Z 2021-09-08T07:15:12Z 2022 http://purl.org/coar/resource_type/c_6501 0301-679X https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=164582 https://hdl.handle.net/20.500.11984/5372 eng Attribution 4.0 International http://creativecommons.org/licenses/by/4.0/ © 2021 The Author(s) Elsevier Ltd.
