Ikke-lineære elementanalyser med en multi-level assessment tilnærmingsmåte på dekker av armert betong
(Master thesis, 2015)I denne oppgaven er det utført en multi level assessment for å finne kapasiteten på to betongdekker, der analyser med økende grad av kompleksitet blir utført. Analysemetodene som er brukt blir vurdert og sammenlignet. To ... -
Ikke-lineære seismiske analyser av plane, momentstive trerammer med duktile søyle-bjelke forbindelser
(Master thesis, 2020)Sammendrag Denne masteroppgaven er en del av forskningsprosjektet Woodsol. Hensikten med oppgaven er å utvikle stålforbindelser til momentstive trerammer, som er duktile nok til å motstå jordskjelv. Oppgaven bygger videre ... -

Impact against coated offshore steel pipes
(Master thesis, 2017)This thesis is part of an ongoing research program between SIMLab and Statoil about impacts on coated offshore pipelines. Impact loads may occur from objects such as anchors or trawls, causing severe damage to the pipe ... -
Impact against empty and water-filled X65 steel pipes - Experiments and simulations
(Journal article; Peer reviewed, 2014)Offshore pipelines are frequently subjected to accidental impact loads, e.g. from anchors or trawl gear. A lot of parameters – including the pipe geometry, material properties, pipeline content, impact velocity, etc. – ... -
Impact Against Offshore Pipelines
(Master thesis, 2013)Impact against offshore pipelines is investigated in this thesis. Introductory low velocity experiments on pipeline specimens using the stretch bending rig at the Department of Structural Engineering, NTNU, were carried ... -
Impact against offshore pipelines
(Master thesis, 2011)In 2007 a pipe at the Kvitebjørn oil field was impacted by an anchor and dragged out of its position. After the accident it was decided safe to run production, but later a leakage was found and the production was shut down. ... -
Impact against offshore pipelines
(Master thesis, 2010)In this thesis impact loads against offshore pipelines are studied. Impact loads are often associated with accidents, such as an anchor hooking. A pipeline subjected to an anchor hooking may experience severe deformations ... -
Impact Against Offshore Pipelines: Experiments and Numerical Simulations
(Master thesis, 2012)In the present thesis impact against offshore pipelines was studied. Incipient fracture in the pipes after impact was of special interest. The present work was a continuation of previous theses on the subject, and part of ... -
Impact against X65 offshore pipelines
(Doctoral thesis at NTNU;2014:362, Doctoral thesis, 2014)This thesis presents both experimental and numerical investigations into some of the plethora of parameters influencing pipeline impact behaviour and the potential fracture arising thereof. The seamless pipes studied are ... -
Impact against X65 steel pipes - An experimental investigation
(Journal article; Peer reviewed, 2013)Offshore pipelines subjected to accidental loads, such as impacts from trawl gear or anchors, may experience large global displacements from its initial position and large local strains. The axial forces set up during ... -
Impact behavior of high-strength steel at low temperatures
(Chapter, 2018)A wide range of material and ballistic tests were conducted to explore the behavior of a high-strength steel at low temperatures. Our test program included quasi-static and dynamic uniaxial and notched tension tests, Charpy ... -
Impact behaviour of foam-based protective structures
(Master thesis, 2017)Foams are three dimensional cellular materials, with cell walls made up of a solid or liquid material and cells containing a gas or liquid. The solid material can be anything from a metal to a ceramic. Metallic and polymeric ... -
Impact Behaviour of Steel at Low Temperatures
(Master thesis, 2017)This thesis represents a continuation of the work carried out by Susanne Thomesen during her master's thesis in 2016. The primary objectives in this thesis were to determine the ballistic properties of the high strength ... -
Impact Behaviour of Steel at Low Temperatures
(Master thesis, 2016)The main objective of this thesis was to determine the impact behaviour of the high strength steel Strenx-960-Plus at room and low temperatures, and to investigate if the deformation and failure mode changed from ductile ... -
Impact behaviour of stiffened aluminium plates
(Master thesis, 2015)In this master thesis, impact loading against stiffened aluminium plates of the aluminium alloy AA6082-T6 was studied. The main objective was to study the behaviour of extruded aluminium profiles welded together when exposed ... -
Impact Behaviour of Stiffened Aluminium Plates
(Master thesis, 2016)In this master thesis stiffened aluminium plates of the aluminium alloy AA6082 subjected to impact loading was studied. The main objective was to study the behaviour of welded and stiffened aluminium plates exposed to ... -
Impact behaviour of stiffened steel plates
(Master thesis, 2015)The impact behavior of stiffened steel plates subjected to impact loading from concentrated loads was studied experimentally and numerically. Both dynamic and quasi-static tests of stiffened steel plates with geometry ... -
Impact Loading on Parts made of Injection-moulded PP
(Master thesis, 2015)This project is set as a part of the ongoing development of the constitutive model the SIMLab Polymer Model (SPM) developed at SIMLab, NTNU. The goal with this thesis is to explore the capabilities of this model using two ...
