    • Drawbead uplift force analytical model for deep drawing operations 

      Gil Acedo, Imanol; Galdos Errasti, Lander; Mendiguren Olaeta, Joseba; Otegi Martínez, Nagore; Saénz de Argandoña, Eneko (IOP Publishing Ltd., 2018)
      Drawbead uplift force calculation has been an open issue among the deep drawing tool maker and software developers in the last years. Starting from the original work of Stoughton (1988) many have been the models presented ...
    • Experimental and Numerical Simulation Investigation on Deep Drawing Process of Inconel 718 with and without Intermediate Annealing Thermal Treatments 

      Ulibarri Hernández, Unai; Galdos Errasti, Lander; Saénz de Argandoña, Eneko; Mendiguren Olaeta, Joseba (MDPI AG, 2020)
      The aeronautical industry is moving from high-capacity large-airplane construction to low-capacity small-airplane construction. With the change in the production volume, there is a need for more e cient manufacturing ...
    • Near Solidus Forming (NSF): Semi-Solid Steel Forming at High Solid Content to Obtain As-Forged Properties 

      Lozares Abasolo, Jokin; Plata Redondo, Gorka; Hurtado Hurtado, Iñaki; Sánchez Fernández, Andrea (MDPI AG, 2020)
      Near solidus forming (NSF) of steels is a novel process under the umbrella of semi-solid forming technologies midway between classical hot forging and semi-solid technologies. This article presents the work done at Mondragon ...
    • Numerical simulation of U-Drawing test of Fortiform 1050 steel using different material models 

      Galdos Errasti, Lander; Saénz de Argandoña Fernández de Gorostiza, Eneko; Mendiguren Olaeta, Joseba; Mugarra Fernandez, Endika; Ulibarri Hernández, Unai (Elsevier Ltd., 2017)
      Steel has been used in vehicles from the automotive industry's inception. Different steel grades are continually being developed in order to satisfy new fuel economy requirements. For example, advanced high ...
    • On the accurate characterization of the drawbead up-lift forces 

      Gil Acedo, Imanol; Galdos Errasti, Lander; Otegi Martínez, Nagore; Mendiguren Olaeta, Joseba; Saénz de Argandoña, Eneko (IOP Publishing Ltd., 2018)
      The competitiveness of the automotive sector has led to a high demand of accuracy and reduction in lead-time of the deep drawing tool making process. In that regard, the numerical simulation of the deep drawing process has ...
    • Press hardening of alternative materials: conventional high- strength steels 

      Mendiguren Olaeta, Joseba; Herrero Dorca, Nuria; Galdos Errasti, Lander; Saénz de Argandoña Fernández de Gorostiza, Eneko (Springer Nature, 2017)
      he increase in strength of new high strength steels(HHS) and advanced high strength steels (AHHS) has led toforming issues, such as high springback, low formability, increase of forming forces and tool wear. These problems ...
    • Study on the influence of the springback on the hole expansion ratio characterization 

      Zubia Arrizabalaga, Biotza; Mendiguren Olaeta, Joseba; Galdos Errasti, Lander; Saénz de Argandoña Fernández de Gorostiza, Eneko; Agirre Bikuña, Julen (Whioce Publishing, 2018)
      Material formability has become one of the main problems, together with the springback, when stamping high added-value components for the automotive industry. The pursuit of weight reduction has led to higher strength ...
