• Ballistic impact of structural steels at low temperatures 

      Holmen, Jens Kristian; Thomesen, Susanne; Perez-Martin, Maria Jesus; Hopperstad, Odd Sture; Børvik, Tore (Peer reviewed; Journal article, 2022)
      Steels are usually stronger at low temperatures than at high temperatures. But low temperatures are, particularly in combination with high strain rates and high stress triaxiality ratios, known to cause embrittlement. The ...
    • Dynamic Behaviour of a High-Strength Structural Steel at Low Temperatures 

      Perez-Martin, Maria Jesus; Holmen, Jens Kristian; Thomesen, Susanne; Hopperstad, Odd Sture; Børvik, Tore (Journal article; Peer reviewed, 2019)
      The main objective of this experimental study is to determine the effect of low temperatures on the mechanical behaviour of Strenx 960 Plus high-strength structural steel at different strain rates and stress triaxialities. ...
    • Fracture mechanisms in largely strained solids due to surface instabilities 

      Erice, Borja; Perez-Martin, Maria Jesus; Kristoffersen, Martin; Morin, David; Børvik, Tore; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2020)
      The effect of self-contacting surface defects generated by largely compressing metals on the ductile-to-brittle transition observed in metallic structures is investigated. In order to analyse such an effect, a finite element ...
