Testing of Fibre Reinforced Concrete Structures: Shear Capacity of Beams with slender Webs
(Master thesis, 2013)Steel fibres in concrete beams have proven to be efficient with regards to take shear forces,and could become a competitor to today?s stirrups. This master?s thesis evaluates positiveand negative effects of having fibre ... -
Testing of Fibre Reinforced Concrete Structures: Structural Behaviour in the Serviceability and Ultimate Limit States
(Master thesis, 2012)This master's thesis contains studies on moment capacity of fibre reinforced concrete in load-bearing structures. The primary focus has been testing of full scale beams with steel fibres, both with and without additional ... -
Testing of Fibre Reinforced Concrete: Shear Capacity of I-Beams
(Master thesis, 2013)A series of full-scale steel fibre reinforced I-beams with varying web width has been tested in shear failure. A rectangular steel fibre reinforced beam and a conventionally reinforced I-beam have also been tested for ... -
Testing of the Johnson-Cook material model VPJC in EUROPLEXUS
(EUR;, Research report, 2015)This document presents some numerical tests for the verification of the Johnson-Cook material model(VPJC) recently introduced in the EUROPLEXUS code (EPX).EUROPLEXUS [1] is a computer code jointly developed by the French ... -
Testing og modellering av tykke støpte aluminiumkomponenter utsatt for støtlast
(Master thesis, 2019)Formålet med denne avhandlingen er å gjennomføre eksperimentell testing av støpt aluminiumfelg utsatt for dynamisk krasjbelastning. Basert på dette vil en numerisk modell bli etablert og brukt for numerisk validering. En ... -
Tests and numerical simulations of polymer components
(Master thesis, 2010)This thesis presents a material model for thermoplastics in LS-Dyna. As SIMLab at NTNU is involved in developing the improved model, they have initiated this thesis. The focus is validating the constitutive model for ... -
Tests and numerical simulations of polymer components: Numerical validation of a constitutive material model for thermo plastics
(Master thesis, 2010)A new constitutive material model intended for thermo plastics, developed at NTNU, was studied in this thesis. The model is implemented as a user-defined material in the finite element code LS-DYNA. For calibration and ... -
Texture gradients and strain localisation in extruded aluminium profile
(Journal article; Peer reviewed, 2016)Through-thickness crystallographic texture gradients may develop in extruded profiles and rolled sheets of aluminium alloys. These texture gradients are often modelled using the crystal plasticity theory in order to predict ... -

(Master thesis, 2021)Abstract will be available on 2024-06-29 -
The behavior of hydrophobic-core/hydrophilic-shell structured microgels at an interface: From Mickering emulsion to colloidosomes with dual-level controlled permeability
(Journal article; Peer reviewed, 2016)A bottom-up approach was empolyed to prepare colloidosomes with dual-level controlled permeability. Starting from the monodisperse poly-2,2,2-trilfuoroethyl methacrylate (PTFMA) core, different size of microgels were ... -
The Coupling Effect of Lead and Polishing Treatments on the Passive Films of Alloy 690TT in High-Temperature and High-Pressure Water
(Journal article; Peer reviewed, 2019)In pressurized water reactors, the existence of lead contamination can promote the corrosion of Alloy 690TT. During the manufacturing, transportation, and assembly processes, Alloy 690TT surface is easily scratched and it ... -
The Digital Workflow of Parametric Structural Design - Developing Grid Shells in a Nordic Climate
(Master thesis, 2018)Unusual shapes are becoming more and more prevalent in the cityscape, however they often rely on large and complex configurations of material. New and empowered digital tools - parametric modelling software - allow for ... -
The effect of accelerated ASR on the mechanical properties and degree of damage of concrete over time - with and without uniaxial compressive stress
(Master thesis, 2018)The aim of this master thesis is to investigate the effect on mechanical properties and degree of damage in concrete exposed to accelerated Alkali-silica reaction (ASR) and uniaxial com-pressive stress, and test if the ... -
The effect of artificial leaching with HCl on chloride binding in ordinary Portland cement paste
(Journal article; Peer reviewed, 2020)This study investigates how the pH in the pore solution influences the chloride binding in Portland cement pastes. Cement paste samples were exposed to NaCl, CaCl2 and HCl solutions. The mechanisms of changes in chloride ... -
The effect of calcium lignosulfonate on ettringite formation in cement paste
(Journal article; Peer reviewed, 2018)The effect of a softwood calcium lignosulfonate, LSs, on the ettringite formed in cement paste was investigated. Two Portland cements, mainly differing in surface area and C3A content, were used. The effect of LSs addition ... -
The Effect of Fiber Reinforcement on Crack Development due to Restraint of Concrete Structures
