Influence of stress triaxiality and strain rate on stress-strain behaviour and dilation of mineral-filled PVC
(Journal article; Peer reviewed, 2019)The influence of stress triaxiality and strain rate on the tensile behaviour of mineral-filled polyvinyl chloride (PVC) is investigated in this paper. Axisymmetric notched tensile specimens with notch radius equal to 20 mm, ... -
Durability aspects of cracks in concrete: field observations
(Chapter, 2019)The research presented in this paper briefly summarises findings from a project on impact of cracks on reinforcement corrosion within the Norwegian Public Roads Administration’s R&D program “Ferry-free coastal route E39”. ... -
Effect of heat-treatment on the structural response of blast-loaded aluminium plates with pre-cut slits
(Journal article; Peer reviewed, 2019)This study investigates the structural response of blast-loaded aluminium plates with pre-cut slits. The 1.5 mm thick plates were tested after three different heat-treatments and with four different pre-cut slit geometries ... -
Finite element modeling of porous polymer pipeline coating using X-ray micro computed tomography
(Journal article; Peer reviewed, 2019)Offshore pipelines are designed to sustain impact from fish trawl equipment and anchors, but due to component complexity, insulating coating solutions are often neglected in mechanical capacity estimates. In this work, ... -
Effective behaviour of porous ductile solids with a non-quadratic isotropic matrix yield surface
(Journal article; Peer reviewed, 2019)In this study, we examine the macroscopic yielding of isotropic porous ductile solids having a matrix yield function dependent on the second and third deviatoric stress invariants. Numerical limit analyses using a ... -
Numerical study of ductile failure under non-proportional loading
(Journal article; Peer reviewed, 2019)This paper investigates two numerical methods for predicting the initiation of ductile failure under moderately and strongly non-proportional loading paths. Two distinct phenomena are considered as indicators for the ... -
A two-stage numerical analysis approach for the assessment of the settlement response of the pre-damaged historic Hoca Pasha Mosque
(Journal article; Peer reviewed, 2019)The current article presents a case study of the settlement response of the historic Hoca Pasha Mosque that involves uncertainties arising from the complex excavation activities, soil properties, building materials, and ... -
Simultaneous optimization of shape and topology of free-form shells based on uniform parameterization model
(Journal article; Peer reviewed, 2019)In current optimization methods for free-form shells, the shape and topology are usually optimized separately. These methods are based on the assumption that the shape and topology of a shell influence each other only ... -
Reactivity tests for supplementary cementitious materials: RILEM TC 267-TRM phase 1
(Journal article; Peer reviewed, 2018)A primary aim of RILEM TC 267-TRM: “Tests for Reactivity of Supplementary Cementitious Materials (SCMs)” is to compare and evaluate the performance of conventional and novel SCM reactivity test methods across a wide range ... -
Comparing chloride ingress from seawater and NaCl solution in Portland cement mortar
(Journal article; Peer reviewed, 2019)This study investigates whether chloride ingress testing can be done using NaCl solution instead of seawater when assessing the performance of concrete in marine conditions. Seawater contains besides sodium and chlorine ... -
A review of literature and code requirements for the crack width limitations for design of concrete structures in serviceability limit states
(Journal article; Peer reviewed, 2019)This paper includes a critical review of the literature related to design of reinforced concrete structures in the serviceability limit state (SLS), and attempts to tie the results to code requirements. The main attention ... -
High strength polymer/silicon nitride composites for dental restorations
(Journal article; Peer reviewed, 2019)Objectives To fabricate polymer-infiltrated silicon nitride composite (PISNC) and evaluate the potential of PISNC in dental application. Methods Porous silicon nitride (Si3N4) ceramics were fabricated through gelcasting ... -
AXITOM: A Python package for reconstruction of axisymmetric tomograms acquired by a conical beam
(Journal article; Peer reviewed, 2019)The ability to picture the internals of a body in a non-invasive way is vital for both diagnostics and research in a broad range of fields. Tomography is the imaging of body sections, typically acquired from projections ... -
Nanostructuring Cu Surfaces for Efficient CO2 Condensation
(Master thesis, 2019)Utvikling av nye metoder for CO2-fangst i industrien, såkalt CO2-håndtering (CCS), er avgjørende for å kunne redusere effektene av global oppvarming i fremtiden. Kondensering av CO2 foregår i flere deler av de ulike ... -
