An experimental and numerical study on the volume change of particle-filled elastomers in various loading modes
(Journal article; Peer reviewed, 2017)Laboratory tests show that there is a pronounced difference in the volumetric response between uniaxial tension and confined axial compression loading for commercial particle-filled hydrogenated nitrile butadiene rubber ... -
Behavior of PVC and HDPE under highly triaxial stress states: An experimental and numerical study
(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
(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 ... -
Influence of strain rate and temperature on the mechanical behaviour of rubber-modified polypropylene and cross-linked polyethylene
(Journal article; Peer reviewed, 2017)In the present work, we investigate the effects of strain rate (e˙=0.01 s−1, 0.1 s−1, and 1.0 s−1) and low temperature (T=−30 °C, −15 °C, 0 °C, and 25 °C) on the mechanical behaviour in tension and compression of two ... -
A multi-barrier model assisted CAFE method for predicting ductile-to-brittle transition with application to a low-carbon ultrahigh-strength steel
(Peer reviewed; Journal article, 2020)The conventional micromechanical approaches today are still not able to properly predict the ductile-to-brittle transition (DBT) of steels because of their inability to consider the co-operating ductile fracture and cleavage ... -
Nanoscale modelling of combined isotropic and kinematic hardening of 6000 series aluminium alloys
(Peer reviewed; Journal article, 2020)Kinematic hardening is incorporated into a nanoscale model for 6000 series aluminium alloys consisting of three sub-models describing in turn precipitation of hardening particles, yield strength and work hardening. The ... -
Work-hardening and ductility of artificially aged AA6060 aluminium alloy
(Journal article; Peer reviewed, 2016)The work-hardening and ductility of an artificially aged AA6060 aluminium alloy were studied based on tensile tests of smooth and notched cylindrical samples. The alloy was tested after three processing steps, each followed ... -
X-ray computed tomography investigation of dilation of mineral-filled PVC under monotonic loading
(Peer reviewed; Journal article, 2019)The deformation-induced dilation of mineral-filled polyvinyl chloride (PVC) is investigated by means of polychromatic X-ray absorption tomography (XCT). Axisymmetric notched tensile specimens are strained to prescribed ...
