(Peer reviewed; Journal article, 2021)This research work investigated in detail the mechanical performance of a flow-drill screw connection of two aluminium plates with and without pilot holes. An extensive experimental campaign involving material and joint ... -
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 ... -
On the Material Characterization of an Aluminium Alloy Using Different Specimens and Identification Methods
(Journal article; Peer reviewed, 2018)The validity of material properties obtained from uniaxial tension tests using different specimen types and measurement techniques is investigated in this paper. Four different specimen geometries were tested, including ... -
On the mechanisms of consumption of calcium lignosulfonate by cement paste
(Journal article; Peer reviewed, 2017)The aim of this paper is to assess the mechanisms of consumption of softwood calcium lignosulfonate (LSs) by cement paste. The LSs consumption by two different cements (CX and ANL) and two reference materials (CaCO3 and ... -
On the Possibilities of Grid Shells - Conceptual design of an elongated grid shell
(Master thesis, 2016)Shell structures has for a long time fascinated both architects and structural engineers alike, since interesting geometries as well as incredible structural soundness is possible to achieve with them. The analysis of shell ... -
On the probabilistic representation of the wind climate for calibration of structural design standards
(Journal article; Peer reviewed, 2018)The article presents a contribution to the current debate on the probabilistic representation of the wind speed extremes for calibration of the partial safety factor covering wind action. The requirements for the probabilistic ... -
On the quasi-incompressible finite element analysis of anisotropic hyperelastic materials
(Journal article; Peer reviewed, 2018)Quasi-incompressible behavior is a desired feature in several constitutive models within the finite elasticity of solids, such as rubber-like materials and some fiber-reinforced soft biological tissues. The Q1P0 finite ... -
On the shear capacity of steel plate girders with large web openings
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:9, Doctoral thesis, 2004)This report presents an investigation of the shear capacities of steel plate girders with web holes, penetrations, cut-outs or openings. The study is motivated by the need for simple guidelines that can be used in practical ... -
