(Master thesis, 2018)This thesis investigates the behavior of deformable steel plates exposed to blast-loading, using experimental two numerical studies. The numerical work consists of a preliminary study and a numerical study with more realistic ... -
Experimental and theoretical investigation of crack width calculation methods for RC ties
(Journal article; Peer reviewed, 2018)This paper theoretically and experimentally investigates the semi-empirical formulas recommended by Eurocode 2 (EC2), fib Model Code 2010 (MC2010), and Eurocode 2 with the German National Annex (DIN) for calculating crack ... -
Experimental carbonation study for a durability assessment of novel cementitious materials
(Peer reviewed; Journal article, 2021)Durability predictions of concrete structures are derived from experience-based requirements and descriptive exposure classes. To support durability predictions, a numerical model related to the carbonation resistance of ... -
Experimental characterization and modeling of aluminum alloy AA3103 for complex single and double strain-path changes
(Journal article; Peer reviewed, 2018)The stress-strain behavior of the aluminum alloy AA3103 subjected to single and double strain-path changes (SPCs) is studied experimentally. The experimental program includes compression-tension, tension-tension, rolling-tension ... -
Experimental Characterization and Modelling of the PLC Effect in an AlMg-Alloy
(Peer reviewed; Journal article, 2021)In the present work, uniaxial tension tests have been conducted to study the mechanical response of a commercial Al4.5wt%Mg alloy (AA5182). The measurements range from the strain rate of 10-4 to 100 s-1 at room temperature. ... -
Experimental detection of forming limit strains on samples with multiple local necks
(Journal article; Peer reviewed, 2016)Sheet metal formability is traditionally described by the forming limit curve (FLC). Experimental FLCs are obtained by performing formability tests and determining failure strains. The strains are usually measured either ... -
Experimental detection of the onset of local necking in an aluminium sheet
(Journal article; Peer reviewed, 2014)Forming limit diagrams (FLDs) are widely used to assess metal sheet formability. Experimental FLDs are obtained by performing formability tests and determining failure strains. The standard method for detection of forming ... -

Experimental investigation and numerical modelling of sheet metalformability
(Master thesis, 2011)In the present work the formability of the steel Docol 600DL has been investigated. The main objectives were 1) to execute and interpret an experimental formability test program on a dual-phase high-strength steel(Docol ... -
Experimental investigation and numerical modelling of the mechanical response of a semi-structural polyurethane adhesive
(Journal article; Peer reviewed, 2019)The use of adhesives in load-carrying structures and components has increased recently, especially in the automotive industry. There has been many studies on structural adhesives, but when it comes to semi-structural ... -
Experimental investigation of ASR-affected concrete – The influence of uniaxial loading on the evolution of mechanical properties, expansion and damage indices
(Peer reviewed; Journal article, 2020)The alkali silica reaction (ASR) in concrete causes internal localized swelling and micro cracking, which result in expansion and correlated deterioration of the concrete material. The stress state of the concrete is known ... -
Experimental investigation on axially-loaded threaded rods inserted perpendicular to grain into cross laminated timber
(Journal article; Peer reviewed, 2023)This paper presents an experimental work on axially-loaded threaded rods inserted perpendicular to grain into the narrow face of cross laminated timber (CLT). Penetration length, loading type (tension, compression, fully ... -
Experimental Investigation on Glaze Ice Accretion and Its Influence on Aerodynamic Characteristics of Pipeline Suspension Bridges
(Peer reviewed; Journal article, 2020)Pipeline suspension bridges may experience ice accretion under special atmospheric conditions, and the aerodynamic characteristics of the bridges may be modified by the ice accretion. Under some specific climatic conditions ... -
Experimental investigation on the structural response of RC slabs subjected to combined fire and blast
(Peer reviewed; Journal article, 2021)Reinforced concrete (RC) submerged floating tunnels (SFTs) represent a possible solution for crossing wide, deep fjords, and is considered for the E39 highway route along the Norwegian west coast. With regard to SFTs, the ... -
