Anisotropic tensile failure of metals by the strain localization theory: An application to a high-strength aluminium alloy
Morin, David; Fourmeau, Marion; Børvik, Tore; Benallal, Ahmed; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2018) -
An experimental study on pre-stretched double-chamber 6000-series aluminium profiles subjected to quasi-static and dynamic axial crushing
Qvale, Kristin; Hopperstad, Odd Sture; Reiso, Oddvin; Tundal, Ulf; Marioara, Calin Daniel; Børvik, Tore (Peer reviewed; Journal article, 2020)Automotive crash boxes require a material selection with strength and ductility in a balanced combination. In this work, the behaviour of double-chamber AA6063 and AA6082 aluminium profiles subjected to quasi-static and ... -
Influence of constituent particles on fracture of aluminum alloys under high-triaxiality loading
Dæhli, Lars Edvard Blystad; Olufsen, Sindre Nordmark; Kristensen, Tore Andre; Børvik, Tore; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2023)Single-edge notch bending tests are conducted to study the influence of constituent particles on the fracture resistance of aluminum alloys 6061, 6063, and 6110 under high-constraint loading conditions. The alloys are ... -
Nanoscale modelling of combined isotropic and kinematic hardening of 6000 series aluminium alloys
Myhr, Ole Runar; Børvik, Tore; Marioara, Calin Daniel; Wenner, Sigurd; Hopperstad, Odd Sture (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 ... -
On the strength-ductility trade-off in thin blast-loaded steel plates with and without initial defects – An experimental study
Elveli, Benjamin Stavnar; Iddberg, Mads Bakken; Børvik, Tore; Aune, Vegard (Peer reviewed; Journal article, 2022)An increase in material strength is commonly associated with better protection in blast-resistant design. However, higher material strength comes at the cost of reduced ductility, and it is still not clear how this trade-off ... -
The relation between grain boundary precipitate formation and adjacent grain orientations in Al-Mg-Si(-Cu) alloys
Marioara, Calin Daniel; Børvik, Tore; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2021)The occurrence of grain boundary precipitates was investigated with respect to the crystallographic orientation of the adjacent grains in extruded AA6110, AA6063 and AA6061 alloys brought to T6 temper. It was found that ... -
Simulation of large-strain behaviour of aluminium alloy under tensile loading using anisotropic plasticity models
Khadyko, Mikhail; Dumoulin, Stephane; Børvik, Tore; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2015)Cylindrical smooth and notched AA6060 samples were tested in tension. The material was either cast and homogenised or extruded with strong cube texture. The textured specimens demonstrated unusual shapes of the fracture ... -
A study of the influence of precipitate free zones on the strain localization and failure of the aluminium alloy AA7075-T651
Fourmeau, Marion; Marioara, Calin Daniel; Børvik, Tore; Benallal, Ahmed; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2015)Age-hardened aluminium alloys have various degrees of precipitate-free zones (PFZs) along grain boundaries (GBs). The PFZs are weak zones and their existence promotes combined transgranular and intergranular fracture, thus ...
