Critical Speed for the Dynamics of Truck Events on Bridges with a Smooth Road
(Journal article; Peer reviewed, 2010)Simple numerical models of point loads are used to represent single and multiple vehicle events on two-lane bridges with a good road profile. While such models are insufficiently complex to calculate dynamic amplification ... -
Maximum dynamic stress on bridges traversed by moving loads
(Journal article; Peer reviewed, 2015)Most current research on dynamic effects due to traffic load on simply supported bridges is focused on the mid-span section of the bridge because this location corresponds to the worst static bending moment. However, the ... -
Sintering properties of sol–gel derived lithium disilicate glass ceramics
(Journal article; Peer reviewed, 2018)Lithium disilicate (Li2Si2O5) glass-ceramics were fabricated through two sol–gel methods: the nitrate route and the alkoxide route. Thermal analysis revealed different crystallization processing of two gel-derived powders. ... -
Analysing limitations of the FlowCyl as a one-point viscometer test for cement paste
(Journal article; Peer reviewed, 2019)The FlowCyl is a simple flow viscometer – a modification of the Marsh Cone test apparatus – developed to quantify the flow behaviour of cement pastes. The FlowCyl gives a one-parameter characterisation of rheology called ... -
Limit states for sustainable reinforced concrete structures
(Journal article; Peer reviewed, 2019)Probability-based limit state design is a hallmark of modern civil engineering practice. Code requirements to meet both ultimate limit states (ULS) and serviceability limit states (SLS) have vastly improved the safety and ... -
On the internal blast loading of submerged floating tunnels in concrete with circular and rectangular cross-sections
(Journal article; Peer reviewed, 2019)The Norwegian Public Roads Administration has initiated a large research project on a potential ferry-free coastal highway route E39 on the west coast of Norway. For the wide and deep fjords, a submerged floating tunnel ... -
Experimental monitoring of bridge frequency evolution during the passage of vehicles with different suspension properties
(Journal article; Peer reviewed, 2019)The natural frequencies of coupled vehicle-bridge systems change with vehicle position. These changes are generally attributed to the contribution of the additional mass of the vehicle. However, other mechanical properties ... -

(Research report, 2019)The report gives an overview of requirements and recommendations to frost durable concrete in standards and specifications, available to the author from a limited selection of standardization and engineering organizations ... -
The effect of ice type on ice adhesion
(Journal article; Peer reviewed, 2019)To lower the ice adhesion strength is the most efficient technique for passive ice removal for several applications. In this paper, the effect of different types of ice on the ice adhesion strength was investigated. The ... -
Mineralogical Sequence of Self-Healing Products in Cracked Marine Concrete
(Journal article; Peer reviewed, 2019)Self-healing of cracked concrete beams after 25 years of marine exposure was investigated. The extent of self-healing and the chemical and mineralogical composition of the self-healing products were characterized, and ... -
Giant Stretchability and Reversibility of Tightly Wound Helical Carbon Nanotubes
(Journal article; Peer reviewed, 2013)There is a surging interest in 3D graphitic nanostructures which possess outstanding properties enabling them to be prime candidates for a new generation of nanodevices and energy-absorbing materials. Here we study the ... -
Phase transition enabled durable anti-icing surfaces and its DIY design
(Journal article; Peer reviewed, 2019)Generally, the longevity and durability of slippery liquid infused porous surfaces (SLIPS) applied for anti-icing purpose are of great challenge. In this work, phase transformable slippery liquid infused porous surfaces ... -
Substrate slip steps promote cracking and buckling of thin brittle film
(Journal article; Peer reviewed, 2019)Cracking and buckling are the two major failure phenomena of brittle film/metal substrate structures. Herein, by depositing titanium nitride brittle films with strong and poor adhesion on stainless steel substrates, we ... -
Cohesive zone simulation of grain size and misorientation effects on hydrogen embrittlement in nickel
(Journal article; Peer reviewed, 2017)The size and misorientation effects on hydrogen embrittlement of a four grain nickel aggregate are studied with the help of hydrogen informed cohesive zone model. The grain misorientation angle is parameterized by fixing ... -
High temperature brittle film adhesion measured from annealing-induced circular blisters
(Journal article; Peer reviewed, 2017)Testing high temperature brittle film adhesion is necessary for understanding interfacial failure at elevated temperatures. However, current brittle film adhesion measurement methods are limited to room temperature. ... -
Structural Instability and Mechanical Properties of MoS2 Toroidal Nanostructures
