    • 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 ...
    • Analysis of different inhibitors for magnesium investment casting 

      Herrero Dorca, Nuria; Hurtado Hurtado, Iñaki; Arruebarrena, Gurutze; Sarriegi Etxeberria, Haritz (IOP Publishing, 2011)
      Investment casting of magnesium is a well suited process for the production of aeronautic and automotive components. But still, this process has not been properly developed. One reason for that are the reactions between ...
    • 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; Sánchez 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 Martínez, 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 ...
    • Initiation of dynamic recrystallization of as-cast N08028 alloy 

      Mora Serrano, Elena; Mendiguren, Joseba; Hurtado, Iñaki (ESAFORM, 2021)
      The use of high nickel content austenitic stainless steels (SASS) has significantly increased in the last decade. The corrosion and high fatigue resistance of these materials make them suitable for manufacturing oil country ...
    • Roll levelling semi-analytical model for process optimization 

      Silvestre Soriano, Elena; GALDOS, Lander; Saénz de Argandoña Fernández de Gorostiza, 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; Saénz de Argandoña Fernández de Gorostiza, 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 ...
