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 ... -
Plastic deformation and fracture of polymer materials
Dahlen, Anfrid (Master thesis, 2011)Polymer materials are known to dilate during plastic deformation. This thesis is a study on some of the mechanisms behind the volume change and how it is affected by triaxiality in stress. The goal was to assess how the ...
