The effect of constituent particles on the tear resistance of three 6000-series aluminium alloys
(Peer reviewed; Journal article, 2022)This paper investigates the tear resistance of three cast and homogenized 6000-series alloys, namely AA6061, AA6063 and AA6110, all in temper T6, by means of Kahn tear tests. Of each alloy one commercial version and one ... -
Finite element simulation of ductile fracture in polycrystalline materials using a regularized porous crystal plasticity model
(Peer reviewed; Journal article, 2021)In the present study, a hypoelastic–plastic formulation of porous crystal plasticity with a regularized version of Schmid’s law is proposed. The equation describing the effect of the voids on plasticity is modified to allow ... -
Influence of pre-compression on the ductility of AA6xxx aluminium alloys
(Journal article; Peer reviewed, 2017)Reversed loading experiments were conducted to study the influence of pre-compression on the ductility of three aluminium alloys. Diabolo-shaped specimens were machined from extruded profiles along the transverse direction, ... -
Micromechanical modelling of ductile fracture in pipeline steel using a bifurcation-enriched porous plasticity model
(Peer reviewed; Journal article, 2021)In this paper, we investigate the possibility of predicting ductile fracture of pipeline steel by using the Gurson–Tvergaard–Needleman (GTN) model where the onset of void coalescence is determined based on in situ bifurcation ... -
Numerical study on the effect of the Lüders plateau on the ductile crack growth resistance of SENT specimens
(Journal article, 2018)The increasing demand of energy prompts the petroleum industry exploitation activities to the Arctic region where the low temperature is a strong challenge, both for structural design and material selection. For structural ... -
On the description of ductile fracture in metals by the strain localization theory
(Journal article; Peer reviewed, 2017)Numerical simulations based on the bifurcation and imperfection versions of the strain localization theory are used in this paper to predict the failure loci of metals and applied to an advanced high strength steel subjected ... -
Simulation of ductile crack propagation in dual-phase steel
(Journal article; Peer reviewed, 2013)The modified Mohr–Coulomb and the extended Cockcroft–Latham fracture criteria are used in explicit finite-element (FE) simulations of ductile crack propagation in a dual-phase steel sheet. The sheet is discretized using ... -
Supergiant elasticity and fracture of 3D spirally wound MoS2
(Peer reviewed; Journal article, 2020)Recently experimentally synthesized three-dimensional (3D) MoS2 spiral is a new kind of helical structure with technically robust properties. Among them, the mechanical properties of such appealing materials are indispensable ...
