    • Fracture resistance of advanced high-strength steel sheets for automotive applications 

      Frómeta Gutiérrez, David; Lara, Antoni; Grifé, Laura; Dieudonné, Thomas; Dietsch, Pascal; Rehrl, Johannes; Suppan, Clemens; Casellas Padró, Daniel; Calvo Muñoz, Jessica (2021-01-03)
      Article
      Open Access
      The fracture resistance of different advanced high strength steel (AHSS) sheets for automotive applications is investigated through conventional tensile tests, fracture toughness measurements and hole expansion tests. ...

    • Fracture toughness to understand stretch-flangeability and edge cracking resistance in AHSS 

      Casellas Padró, Daniel; Lara, Antoni; Frómeta Gutiérrez, David; Gutierrez Castillo, David; Molas Busquets, Sílvia; Pérez Caro, Lluís; Rehrl, Johannes; Suppan, Clemens (2016-10-20)
      Article
      Open Access
      The edge fracture is considered as a high risk for automotive parts, especially for parts made of advanced high strength steels (AHSS). The limited ductility of AHSS makes them more sensitive to the edge damage. The ...

    • Microstructural effects on fracture toughness of ultra-high strength dual phase sheet steels 

      Frómeta Gutiérrez, David; Cuadrado Lafoz, Nuria; Rehrl, Johannes; Suppan, Clemens; Dieudonné, Thomas; Dietsch, Pascal; Calvo Muñoz, Jessica; Casellas Padró, Daniel (2021-01-20)
      Article
      Open Access
      The influence of the microstructure on the fracture toughness of two industrially processed 1000 MPa dual-phase (DP) steel grades is investigated. Crack initiation and propagation resistance are evaluated by means of the ...

    • On the correlation between fracture toughness and crash resistance of advanced high strength steels 

      Frómeta Gutiérrez, David; Lara, Antoni; Molas Busquets, Sílvia; Casellas Padró, Daniel; Rehrl, Johannes; Suppan, Clemens; Larour, Patrick; Calvo Muñoz, Jessica (2019-01-01)
      Article
