Experimental and numerical study on the behaviour of PVC and HDPE in biaxial tension
Ognedal, Anne Serine; Clausen, Arild Holm; Polanco-Loria, Mario A.; Benallal, Ahmed; Raka, Bumedijen; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2012)This paper presents and discusses a set of biaxial tests on two different polymer materials; PVC and HDPE. The biaxial tests are used to evaluate a hyperelastic–viscoplastic constitutive model involving the pressure-dependent ... -
A study of the influence of precipitate free zones on the strain localization and failure of the aluminium alloy AA7075-T651
Fourmeau, Marion; Marioara, Calin Daniel; Børvik, Tore; Benallal, Ahmed; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2015)Age-hardened aluminium alloys have various degrees of precipitate-free zones (PFZs) along grain boundaries (GBs). The PFZs are weak zones and their existence promotes combined transgranular and intergranular fracture, thus ...
