Influence of the pressure dependent coefficient of friction on deep drawing springback predictions
(Elsevier Ltd., 2016)
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 ...
Perfilado 4.0: ayuda a la puesta a punto y aseguramiento de la calidad en procesos de perfilado
(2019)
Una problemática a la que se enfrentan las empresas de perfilado de chapa es la laboriosa, y con ello costosa, puesta a punto del proceso. En ella los operarios basan sus decisiones en experiencias pasadas y en la mayoría ...
Characterization of Ti64 forging friction factor using ceramic coatings and different contact conditions
(Elsevier, 2017)
Hot forging processes are highly influenced by the contact conditions between the billet and the dies. A wrong definition of the contact conditions may lead to wrong predictions of the final component geometry, the quantity ...
Hardening prediction of diverse materials using the Digital Image Correlation technique
(Elsevier, 2018)
In recent years, due to the introduction of higher resistance materials in the automotive sector, sheet metal-forming tool-makers have been forced to deal with more challenging process designs. Therefore, the optimisation ...
Hole expansion test of third generation steels
(AIP Publishing, 2017)
The trend towards the implementation of new materials in the chassis of the automobiles is considerably making more complex the manufacturing of the components that built it up. In this scenario materials with higher ...
