Finite Element Implementation of Fibre-Reinforced Materials Model in Abaqus/Explicit
Vestrum, Ole (Master thesis, 2015)This thesis is concerned with the constitutive modelling of short fibre-reinforced composites in the finite element code Abaqus/Explicit. The model is presented as a generic framework which is based on a two-phase ... -
Finite element implementation of lower-order strain gradient plasticity in Abaqus
Heggelund, Teodor Lunaas (Master thesis, 2015)A finite element method implementation of lower-order strain gradient plasticity is developed. Its validity is checked against known analytical solutions. The implementation gives expected trends when applied to particle ... -
Finite element modelling of steel bridge structures exposed to ship collisions
Ofstad, Kevin Mandt (Master thesis, 2018)The behavior of the Bressan-Williams-Hill fracture criterion (BWH), which is often used in simulating ship collisions, was studied by modeling and studying existing experiments done on the subject. Three experiments are ... -
Fracture mechanisms in largely strained solids due to surface instabilities
Erice, Borja; Perez-Martin, Maria Jesus; Kristoffersen, Martin; Morin, David; Børvik, Tore; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2020)The effect of self-contacting surface defects generated by largely compressing metals on the ductile-to-brittle transition observed in metallic structures is investigated. In order to analyse such an effect, a finite element ... -
Impact behaviour of stiffened aluminium plates
Kårstad, Bente Larsen; Skajaa, Birgitte (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

Impact behaviour of stiffened steel plates
Sølvernes, Sindre Hellem (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
Berntsen, John Fredrick (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 ... -
Influence of yield surface curvature on the macroscopic yielding and ductile failure of isotropic porous plastic materials
Dæhli, Lars Edvard; Morin, David; Børvik, Tore; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2017)Numerical unit cell models of an approximative representative volume element for a porous ductile solid are utilized to investigate differences in the mechanical response between a quadratic and a non-quadratic matrix yield ... -
