    • R-Curve approach to describe the fracture resistance of tool steels 

      Picas Anfruns, Ingrid; Casellas Padró, Daniel; Llanes Pitarch, Luis Miguel (2016-06)
      Article
      Accés obert
      This work addresses the events involved in the fracture of tool steels, aiming to understand the effect of primary carbides, inclusions, and the metallic matrix on their effective fracture toughness and strength. ...
    • Sheet failure prediction during forming of advanced high strength steels 

      Gutiérrez, D.; Hernández, R.; Riera Colom, María Dolores; Lara, Toni; Casellas Padró, Daniel; Prado Pozuelo, José Manuel (2013)
      Text en actes de congrés
      Accés obert
      The automotive industry has increased significantly the use of advanced high strength steels (AHSS) in many structural components of vehicles, with the aim to reduce weight and also increase safety. The high resistance ...
