The Particle-Matrix model: limitations and further improvements needed
(Journal article; Peer reviewed, 2017)According to the Particle-Matrix Model (PMM) philosophy, the workability of concrete depends on the properties of two phases and the volumetric ratio between them: the fluid matrix phase (≤ 0.125 mm) and the solid particle ... -
The possibility of using reinforcement bars of aluminium in concrete structures
(Master thesis, 2018)In this study, the possibility of using aluminium as reinforcement in concrete structures is investigated, with use of a low pH concrete. The thesis is assigned by NTNU, and is a part of the science project DARE2C, a project ... -
The role of concrete resistivity in chloride-induced macro-cell corrosion of reinforcement
(Doctoral thesis at NTNU;2015:324, Doctoral thesis, 2015)Norwegian concrete structures are exposed to salt contamination from both sea water and de-icing salts. Chlorides penetrate the concrete cover and initiate corrosion of the reinforcement. The deterioration process can ... -
The role of quench rate on the plastic flow and fracture of three aluminium alloys with different grain structure and texture
(Journal article; Peer reviewed, 2020)The yielding, plastic flow and fracture of age hardenable aluminium alloys depend on the quench rate to room temperature after the solution heat-treatment at elevated temperature and before the artificial ageing. We ... -
The Rollout Stress Ribbon Bridge
(Chapter, 2017)THE ROLLOUT STRESS RIBBON BRIDGE Stress ribbon bridges are light and visually elegant. At sites with solid conditions for tension based anchoring, they can also be very economical. This paper presents the concept of a ... -
The Time Varying Elastance Model used as a Boundary Condition in Arterial Network Simulations
(Master thesis, 2013)Vascular1Dflow is a program for simulating blood flow in vascular networks. It uses hyperbolic one-dimensional partial differential equations with ordinary differential equations as boundary conditions. The focus of this ... -
A theoretical study of the dynamic response of planar timber frames with semi-rigid moment-resisting connections subjected to wind loads
(Peer reviewed; Journal article, 2021)The dynamic response of semi-rigid timber frames subjected to wind loads is investigated numerically in this paper. The dynamic response of more than one million unique frames with different parameters was assessed with ... -
Thermal analysis of marine structural steel EH36 subject to non-spreading cryogenic spills: Part III: structural response assessment
(Peer reviewed; Journal article, 2022)An experimental study that allows for thermal-structural analysis of steel structures subject to non-spreading cryogenic spills is described. A local, non-spreading cryogenic spill was replicated by building a liquid ... -
