Experimental analysis of GLULAM specimens from Tretten bridge and related block failure and fatigue issues
(Master thesis, 2023)Målet med denne masteroppgaven er å belyse viktige temaer som kan ha bidratt til kollapsen av Tretten bru, med særlig vekt på trevirkets relasjon til blokkutrivning og utmatting. Det vil bli gjennomført eksperimentelle ... -
An Experimental and Numerical Investigation of the Blast Response of Pre-damaged Aluminium Plates
(Master thesis, 2017)The dynamic response of thin, perforated aluminium plates subjected to blast load has been studied both experimentally and numerically. The experiments have been conducted in a shock tube facility, where the blast intensity ... -
Experimental and Numerical Studies of Plain and Reinforced Concrete Plates Subjected to Blast Loading
(Master thesis, 2016)The main objective in this thesis was to determine how the behavior of concrete structures subjected to blast loads may be predicted. An experimental study was conducted, in which 50 mm thick plain and reinforced concrete ... -
Experimental and numerical studies of tubular concrete structures subjected to blast loading
(Peer reviewed; Journal article, 2021)The E39 coastal highway route along the west coast in Norway is envisioned a future without ferries. A submerged floating tube bridge built in concrete has been suggested as a means of crossing wide and deep fjords, and ... -
Experimental and numerical studies on the structural response of normal strength concrete slabs subjected to blast loading
(Journal article; Peer reviewed, 2018)To assess the blast performance of concrete structures, a shock tube has been used to simulate blast loading against concrete slabs of two different mixes ordered as C45/55 and C20/25. The C45/55 slabs were tested without ... -
An experimental and numerical study of bolt and nut assemblies under tension loading
(Master thesis, 2016)The purpose of this master thesis is to investigate how the nut position affects the failure mode of single tensile loaded bolts under quasi-static conditions. A ductile bolt fracture is preferable from an engineering ... -
Experimental and numerical study of dilation in mineral filled PVC
(Doctoral theses at NTNU;2020:388, Doctoral thesis, 2020)This thesis addresses the link between applied load and dilation caused by void growth in mineral-filled PVC employing both experimental and numerical techniques. The influence of stress triaxiality and strain rate on the ... -
Experimental and Numerical Study of Hybrid Concrete Structures
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:259, Doctoral thesis, 2013)The hybrid concrete structures investigated in this project are beams composed by layers of different types of concrete. Normal density concrete (NC) is used as top (and bottom) layer combined with a layer of fibre reinforced ... -
Experimental and numerical study of mooring chain residual stresses and implications for fatigue life
(Peer reviewed; Journal article, 2020)Residual stresses in large mooring chains were measured for the first time in this study. Two measurement techniques were employed (neutron diffraction and hole drilling). Elastic-plastic finite element simulation of the ... -
Experimental and numerical study of notched SHS made of different S355 steels
(Peer reviewed; Journal article, 2021)This study compares the mechanical behaviour of square hollow sections (SHS) made of three different types of S355: cold-formed, hot-rolled and offshore steel. A material model and failure criterion for each steel type ... -
Experimental and Numerical Study of Sandwich Panels Exposed to Blast Loading
(Master thesis, 2018)The main objective of this thesis is to investigate, both experimentally and numerically, the mechanical response of various sandwich components with foam cores subjected to a range of blast load scenarios. Experiments ... -
An experimental and numerical study of the mechanical behaviour of short glass-fibre reinforced thermoplastics
(Doctoral theses at NTNU;2019:79, Doctoral thesis, 2019)This thesis presents an experimental and numerical investigation of injection-moulded short glass-fibre reinforced thermoplastics subjected to monotonic tensile-dominated quasistatic loadings. Two classes of materials are ... -
