On the effect of plastic anisotropy, strength and work hardening on the tensile ductility of aluminium alloys
(Journal article; Peer reviewed, 2019)The influence of plastic anisotropy, yield strength and work hardening on ductile failure is studied by nonlinear finite element simulations and strain localization analyses of tensile tests in different material orientations. ... -
On the Fluid-Structure Interaction Effects of Plated Structures Subjected to Blast Loading - An Experimental and Numerical Investigation
(Chapter, 2015)An experimental and numerical investigation using a new shock tube facility to study potential fluid-structure interaction (FSI) effects on thin aluminium plates are presented. The shock tube is capable of recreating a ... -
On the fracture locus of ductile materials
(Master thesis, 2011)Predicting the limits for safe use of a material under combined stresses requires the application of a fracture criteria. The stress triaxiality and the equivalent strain to fracture is found to be the most important ... -
On the importance of cross-sectional details in the wind tunnel testing of bridge deck section models
(Journal article; Peer reviewed, 2017)Experimentally derived aerodynamic derivatives are used to predict and prevent undesirable aeroelastic behavior of bridges and are currently considered indispensable in the design of long-span bridges. The aerodynamic ... -
On the importance of tunica intima in the aging aorta: a three-layered in silico model for computing wall stresses in abdominal aortic aneurysms
(Peer reviewed; Journal article, 2020)Layer-specific experimental data for human aortic tissue suggest that, in aged arteries and arteries with non-atherosclerotic intimal thickening, the innermost layer of the aorta increases significantly its stiffness and ... -
On the internal blast loading of submerged floating tunnels in concrete with circular and rectangular cross-sections
(Journal article; Peer reviewed, 2019)The Norwegian Public Roads Administration has initiated a large research project on a potential ferry-free coastal highway route E39 on the west coast of Norway. For the wide and deep fjords, a submerged floating tunnel ... -
