Aluminium plates with pre-formed slits subjected to blast loading
Granum, Henrik; Aune, Vegard; Børvik, Tore; Hopperstad, Odd Sture (Chapter, 2018)The dynamic response of thin, perforated aluminium plates subjected to blast loading was studied both experimentally and numerically. Two different blast intensities were used and the plates were pre-cut with four horizontal ... -
Calibration of the modified Mohr-Coulomb fracture model by use of localization analyses for three tempers of an AA6016 aluminium alloy
Granum, Henrik; Morin, David; Børvik, Tore; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2021)This paper presents a novel calibration procedure of the modified Mohr-Coulomb (MMC) fracture model by use of localization analyses and applies it for three tempers of an AA6016 aluminium alloy. The localization analyses ... -
Effect of heat-treatment on the structural response of blast-loaded aluminium plates with pre-cut slits
Granum, Henrik; Aune, Vegard; Børvik, Tore; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2019)This study investigates the structural response of blast-loaded aluminium plates with pre-cut slits. The 1.5 mm thick plates were tested after three different heat-treatments and with four different pre-cut slit geometries ... -
Modelling, Simulation and Optimization of Crash Components in Aluminium
Solhjem, Espen; Kjus, Eivind Sogn (Master thesis, 2017)The main focus of this thesis was to establish a validated finite element model of an extruded rectangular hollow profile with a single chamber. Experimental axial crushing tests were carried out on various heat treated ... -

Granum, Henrik (Doctoral theses at NTNU;2020:374, Doctoral thesis, 2020) -
Nanostructure-based finite element analyses of aluminium profiles subjected to quasi-static axial crushing
Granum, Henrik; Myhr, Ole Runar; Børvik, Tore; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2018)In this study, a nanostructure model is used to predict the stress-strain curves of the aluminium alloys AA6063, AA6061 and AA6110 in T6, T7 and O tempers based on the chemical composition and the thermo-mechanical history. ... -
Simulation of blast-loaded aluminium plates with crack-like defects
Granum, Henrik; Morin, David; Børvik, Tore; Hopperstad, Odd Sture (Chapter, 2019)This paper presents a numerical study on the response of blast-loaded AA6016 T4 aluminium plates with crack-like defects. Explicit finite element simulations were performed with LS-DYNA, using an uncoupled plasticity and ... -
Static and dynamic crushing of aluminium profiles
Qvale, Kristin (Master thesis, 2018)In this thesis the static and dynamic axial crushing response of an extruded two-chamber aluminium profile geometry have been studied. The materials tested were two aluminium alloys of the 6000-series, AA6063 and AA6082, ...
