A numerical study on the deformation and fracture modes of steel projectiles during Taylor bar impact tests
(Journal article; Peer reviewed, 2014)A heterogeneous material model based on macro-mechanical observations is proposed for simulation of fracture in steel projectiles during impact. A previous experimental study on the deformation and fracture of steel ... -
Aluminum foam-filled extrusions subjected to oblique loading: experimental and numerical study
(Journal article; Peer reviewed, 2004)The behavior of empty and foam-filled square thin-walled aluminum columns in alloy AA6060 subjected to quasi-static oblique loading was examined. Previous studies have shown that by introducing a load angle, the energy ... -
Fracture mechanisms in largely strained solids due to surface instabilities
(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 ... -
Impact against X65 steel pipes - An experimental investigation
(Journal article; Peer reviewed, 2013)Offshore pipelines subjected to accidental loads, such as impacts from trawl gear or anchors, may experience large global displacements from its initial position and large local strains. The axial forces set up during ... -
Influence of loading path on ductile fracture of tensile specimens made from aluminium alloys
(Journal article; Peer reviewed, 2016)Experimental data and numerical simulations of smooth and notched tensile tests on four different aluminium alloys are used to investigate the effect of loading path on ductile fracture. Micromechanical studies are undertaken ... -
Modeling strain-path changes in aluminum and steel
(Journal article, 2017)The present paper evaluates two phenomenological plasticity models which account for the influence of strain-path change (SPC) on the stress-strain behavior. The HAH model (Barlat et al., 2014) is modified to capture SPC ... -
Numerical implementation of a non-local GTN model for explicit FE simulation of ductile damage and fracture
(Journal article, 2021)In this study, we follow the work of Tvergaard and Needleman (1995, 1997) and Needleman and Tvergaard (1998) and present the numerical implementation and initial applications of a non-local Gurson-Tvergaard-Needleman (GTN) ... -

On the effect of plastic anisotropy, strength and work hardening on the tensile ductility of aluminium alloys
(Journal article; Peer reviewed, 2019)The influence of plastic anisotropy, yield strength and work hardening on ductile failure is studied by nonlinear finite element simulations and strain localization analyses of tensile tests in different material orientations. ... -
A pragmatic orthotropic elasticity-based damage model with spatially distributed properties applied to short glass-fibre reinforced polymers
(Peer reviewed; Journal article, 2021)This article presents a simple progressive damage model for quasi-brittle materials, combining orthotropic elasticity with a scalar damage model including spatial variation of the damage initiation strain and the crack ... -
Texture gradients and strain localisation in extruded aluminium profile
(Journal article; Peer reviewed, 2016)Through-thickness crystallographic texture gradients may develop in extruded profiles and rolled sheets of aluminium alloys. These texture gradients are often modelled using the crystal plasticity theory in order to predict ... -
Void nucleation and growth in mineral-filled PVC - An experimental and numerical study
(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. ...
