Behavior of PVC and HDPE under highly triaxial stress states: An experimental and numerical study
Ognedal, Anne Serine; Clausen, Arild Holm; Dahlen, Anfrid; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2014)This paper addresses the deformation of axisymmetric tensile bars, made of mineral-filled PVC and HDPE, with and without pre-machined notch. The purpose of the study is both to investigate the mechanical behavior under ... -
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 (Journal article; Peer reviewed, 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 ... -
Large-Deformation Behaviour of Thermoplastics at Various Stress States: An experimental and numerical study
Ognedal, Anne Serine (Doktoravhandlinger ved NTNU, 1503-8181; 2012:298, Doctoral thesis, 2012)The large-deformation behaviour of thermoplastics has been studied by experimental tests and numerical simulations. The work herein is a part of a larger research project concerning constitutive modelling of polymers. A ... -
Void nucleation and growth in mineral-filled PVC - An experimental and numerical study
Ognedal, Anne Serine; Clausen, Arild Holm; Berstad, Torodd; Seelig, Thomas; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2014)The nucleation and growth of voids in mineral-filled PVC have been investigated through experimental and numerical studies. Uniaxial tensile specimens were deformed in tension to different elongation levels and then unloaded. ...
