Sprayed concrete - effect of accelerator, cracks and composition on compaction, porosity, strength and water transport properties
(Doctoral theses at NTNU;2023:124, Doctoral thesis, 2023)The research described in this PhD thesis investigated key aspects of sprayed concrete material, with an intention of gaining knowledge to enable greater use of sprayed concrete for permanent tunnel linings. The two unique ... -
Sprøytebetong testet med destruktiv og ikke-destruktiv metode
(Master thesis, 2015)Denne oppgaven omhandler schmidthammer og ultralyd brukt på sprøytebetong, i en høytrafikkert tunnel, som er under oppfølging på grunn av sulfatangrep De ikke-destruktive metodene er ikke så vanlig i bruk på sprøytebetong ... -
Square aluminum tubes subjected to oblique loading
(Journal article; Peer reviewed, 2003)The behavior and energy-absorbing capability of obliquely loaded square thin-walled aluminum columns in alloy AA6060 were studied through quasi-static experiments and FEM-analyses with LS-DYNA. The specimens were clamped ... -
The square root method for chloride ingress prediction - Applicability and limitations
(Peer reviewed; Journal article, 2021)A recent observation showed a square root time dependency of the ingress depth of a fixed (reference) chloride concentration of 0.05% chloride by mass of concrete for submerged exposure in Kattegat and the Baltic Sea. The ... -
Stability of matrix for self-compacting concrete: effect of filler and VMA

Stability of the hydrate phase assemblage in Portland composite cements containing dolomite and metakaolin after leaching, carbonation, and chloride exposure
(Journal article; Peer reviewed, 2018)To reduce CO2 emissions during the production of cement and to cope with increasing demands for concrete, and thereby cement, the cement industry needs to identify new supplementary cementitious materials. These new composite ... -
Stability, deformation and rupture of Janus oligomer enabled self-emulsifying water-in-oil microemulsion droplet
(Peer reviewed; Journal article, 2020)Microemulsion exists widely in nature, daily life and industrial manufacturing, including petroleum production, food processing, drug delivery, new materials fabrication, sewage treatment, etc. The mechanical properties ... -
Static Analysis of Fire Water Pump Module
(Master thesis, 2012)This thesis is based on a project from the previous semester (fall 2011) and initiated by Sigve Gjerstad at Frank Mohn Flato y AS. The thesis introduces the FWP system and different aspects regarding a static analysis of ... -
Static and Dynamic Analysis of Conductor Rail with Large Cross-Sectional Moment of Inertia in Rigid Catenary Systems
(Peer reviewed; Journal article, 2023)The rigid catenary system is widely used in tunnels to power electric trains via contact with a pantograph. Due to gravity, the contact wire normally has a sag that may affect the dynamic interaction performance with a ... -
Static and dynamic crushing of aluminium profiles
(Master thesis, 2018)In this thesis the static and dynamic axial crushing response of an extruded two-chamber aluminium profile geometry have been studied. The materials tested were two aluminium alloys of the 6000-series, AA6063 and AA6082, ... -
Static and dynamic response of a structure subjected to ice forces – Evaluation of a lighthouse overloading event
(Master thesis, 2010)Exploitation of areas and natural resources in arctic and sub-arctic areas makes guidelines for designing structures exposed to ice-forces a necessity. Ice actions on a structure include both static and dynamic components, ... -
Static and dynamic testing and modelling of aluminium joints with flow-drill screw connections
(Journal article; Peer reviewed, 2018)A new component test suited for quasi-static and dynamic testing of flow-drill screw connections is presented. The component specimen was made of two different aluminium alloys, and included connections with two material ... -
Static crushing of aluminium tubes filled with PET foam and a GFRP skeleton. Numerical modelling and multiobjective optimization.
(Journal article; Peer reviewed, 2017)This investigation focuses on the multiobjective optimization of a crash box subjected to static loading by using a validated numerical model and an analytical approach. The crash box is made with a unique combination of ... -
Static yield stress measurements on SCC, mortar and matrix
(Research report, 2013)The static yield stress of fresh self-compacting concrete and its time dependency was measured in different materials and conditions/methods. First the BML ConTech4 was used at very slow rotation by analysis of the data ... -
