Accurate drawbead modeling in stamping simulations
Sáenz de Argandoña, Eneko (IOP Publishing, 2016)An adaptive line bead model that continually updates according to the changing conditions during the forming process has been developed. In these calculations, the adaptive line bead's geometry is treated as a 3D object ... -
Characterization of Ti64 forging friction factor using ceramic coatings and different contact conditions
GALDOS, Lander; Mendiguren, Joseba; Sáenz de Argandoña, Eneko; Agirre, Julen (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 ... -
Contact pressure and sliding velocity ranges in sheet metal forming simulations
Cillaurren Arriaga, Joseba; GALDOS, Lander; Sanchez Palomar, Mario; Zabala, Alaitz; Sáenz de Argandoña, Eneko; Mendiguren, Joseba (2021)In the last few years many efforts have been carried out in order to better understand what the real contact between material and tools is. Based on the better understanding new friction models have been developed which ... -
Contact pressure, sliding velocity and viscosity dependent friction behavior of lubricants used in tube hydroforming processes
GALDOS, Lander; Otegi, Nagore; Mendiguren, Joseba; Trinidad Naranjo, Javier; Sáenz de Argandoña, Eneko (2021)The final quality of sheet and tube metal formed components strongly depends of the tribology and friction conditions between the tools and the material to be formed. Furthermore, it has been recently demonstrated that ... -
Hole expansion test of third generation steels
Agirre, Julen; Mendiguren, Joseba; GALDOS, Lander; Sáenz de Argandoña, Eneko (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 ... -
Necking detection in stretch-bent materials exhibiting the Portevin-Le Chatelier effect
Sáenz de Argandoña, Eneko; Mendiguren, Joseba (Materials Research Forum LLC, 2024)In recent years, there has been increasing societal awareness of the carbon dioxide (CO2) footprint resulting from individual actions and lifestyles. One of the research actions is focused on the development of eco-friendly ... -
Perfilado 4.0: ayuda a la puesta a punto y aseguramiento de la calidad en procesos de perfilado
Sáenz de Argandoña, Eneko; GALDOS, Lander; Mendiguren, Joseba; Reguera-Bakhache, Daniel; Garitano, Iñaki (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 ... -
Roll levelling semi-analytical model for process optimization
Silvestre Soriano, Elena; GALDOS, Lander; Sáenz de Argandoña, Eneko; Mendiguren, Joseba (IOP, 2016)Roll levelling is a primary manufacturing process used to remove residual stresses and imperfections of metal strips in order to make them suitable for subsequent forming operations. In the last years the importance of ... -
Sensitivity analysis on an AC600 aluminum skin component
Mendiguren, Joseba; Sáenz de Argandoña, Eneko; GALDOS, Lander; Mugarra Fernandez, Endika (IOP, 2016)New materials are been introduced on the car body in order to reduce weight and fulfil the international CO2 emission regulations. Among them, the application of aluminum alloys is increasing for skin panels. Even if these ... -
Simulation of Cold Forging Processes Using a Mixed Isotropic-Kinematik Hardening Model
GALDOS, Lander; Agirre, Julen; Otegi, Nagore; Mendiguren, Joseba; Sáenz de Argandoña, Eneko (Springer, 2021)Cold forging is a manufacturing process where a bar stock is inserted into a die and squeezed with a second closed die. It is one of the most widely used chipless forming processes, often requiring no machining or additional ... -
Zeharkako ebaketa prozesuaren parametroen eragina erresistentzia handiko altzairuzko xafla lodietan
Abedul Moreno, David; GALDOS, Lander; Sáenz de Argandoña, Eneko (UEU, 2021)Transversal cutting processes are usually employed for metal coil cutting or precut reduction operations. The final result of a cutting operation, in terms of sheared edge quality and process forces, is dependent on the ...
