Anisotropic tensile failure of metals by the strain localization theory: An application to a high-strength aluminium alloy
(Journal article; Peer reviewed, 2018)This paper investigates the influence of plastic anisotropy on the tensile ductility of a high-strength aluminium alloy. To this end, finite element simulations of smooth and notched tension tests in different material ... -
Constitutive modeling of aluminum foam including fracture and statistical variation of density
(Journal article; Peer reviewed, 2003)An existing constitutive model applicable for aluminum foam was evaluated. The model was implemented in LS-DYNA, and several test cases were analyzed and compared to experimental data. The numerical analyses consisted of ... -
Continuum-micromechanical modeling of distributed crazing in rubber-toughened polymers
(Journal article; Peer reviewed, 2016)A micromechanics based constitutive model is developed that focuses on the effect of distributed crazing in the overall inelastic deformation behavior of rubber-toughened ABS (acrylonitrile-butadiene-styrene) materials. ... -
Influence of fragmentation on the capacity of aluminum alloy plates subjected to ballistic impact
(Journal article; Peer reviewed, 2016)In this paper, the perforation resistance of 20 mm thick aluminum plates subjected to moderate velocity impacts is examined experimentally and numerically. Plates made of four different tempers of aluminum alloy AA6070 ... -
Strain localization and ductile fracture in advanced high-strength steel sheets
(Journal article, 2017)An experimental-numerical approach is applied to determine the strain localization and ductile fracture of high-strength dual-phase and martensitic steel sheet materials. To this end, four different quasi-static material ... -
Unit cell simulations and porous plasticity modelling for strongly anisotropic FCC metals
(Journal article; Peer reviewed, 2017)The macroscopic behaviour of anisotropic porous solids made from an aggregate of spherical voids embedded in a plastically anisotropic matrix material is investigated by means of unit cell simulations. Plastic yielding of ...
