Thin steel plates exposed to combined ballistic impact and partially confined airblast loading
(Peer reviewed; Journal article, 2023)Pre-formed defects created by high-velocity impact have the potential to reduce the structural integrity of lightweight, flexible structures. This study evaluates the effect of complex, partially confined detonations on ... -
Revisiting concrete frost salt scaling: On the role of the frozen salt solution micro-structure
(Peer reviewed; Journal article, 2022)We simulate the glue-spall stress due to mechanical interactions between a frozen saline solution (brine-ice composite) and a non-air entrained concrete surface including the impact of the micro-structure of the frozen ... -
Towards the “sustainable” operation at -30 °C without the expense of energy for heating on-face electronics: intelligent heat conservation and waste heat utilization
(Journal article; Peer reviewed, 2022)On-face electronics (On-faceE) are urged to sense “anytime, anywhere” for enabling human senses to globally dominate the Internet of Things. However, with the limited lifetime of batteries and the miniaturization of the ... -
Investigation of leaching in steel fiber-reinforced shotcrete exposed to fresh and saline groundwater in a subsea road tunnel
(Peer reviewed; Journal article, 2022)The field and laboratory investigations performed in the Frøya subsea road tunnel, constructed between 1998 and 2000, focus on the degree of leaching undergone by steel fiber-reinforced shotcrete in fresh and saline ... -
Reconstruction of surface pressures on flat plates impacted by blast waves using the Virtual Fields Method
(Peer reviewed; Journal article, 2023)An accurate description of surface pressure loads imposed by blast waves is crucial for the design of the next generation of blast-resistant structures. However, experimental techniques for non-intrusive, full-field surface ... -
A unified constitutive model for pressure sensitive shear flow transitions in moderate dense granular materials
(Peer reviewed; Journal article, 2021)Granular shear flows exhibit complex transitional regimes that are dramatically affected by the pressure level and shear stress state. New advances in granular shear tests at low pressure have enlightened the understanding ... -
Dynamic strain ageing in an AlMg alloy at different strain rates and temperatures: Experiments and constitutive modelling
(Peer reviewed; Journal article, 2022)Uniaxial tension tests at strain rates from to and temperatures from 298 to 418 K are performed to study the dynamic strain ageing (DSA) of an AA5182-O sheet. Digital image correlation (DIC) is used to obtain the stress-strain ... -
Vehicle assisted bridge damage assessment using probabilistic deep learning
(Peer reviewed; Journal article, 2023)Vehicle assisted monitoring has shown promising potential for the condition assessment of existing bridges in a road network, by removing practical complications faced in traditional Structural health monitoring (SHM) ... -
Feasibility study of reactive mass transport modelling to support service life design: Numerical simulation of chloride ingress
(Research report, 2022)This report discussed the applicability of reactive mass transport (RMT) models for the durability design of concrete structures. The study focussed on supporting service life modeling of chloride-induced reinforcement ... -

A simple method enabling efficient quantitative analysis of the Portevin–Le Chatelier band characteristics
(Peer reviewed; Journal article, 2022)Localized deformation bands are often observed in materials exhibiting the Portevin–Le Chatelier (PLC) effect. However, efficient quantitative analysis of PLC bands remains challenging. A novel method is thus proposed in ... -
Nanoscale creep behavior and its size dependency of a Zr-based bulk metallic glass manufactured by selective laser melting
(Journal article; Peer reviewed, 2022)Nanoscale creep behaviors of metallic glasses (MGs) have gathered considerable interests in recent years, owing to their distinct atomistic mechanisms of plasticity. Additive manufacturing (AM) is a burgeoning technique ... -
Optimization of Shell Structures
(Master thesis, 2022)Skallkonstruksjoner er relativt populært blant folk, men samtidig veldig komplisert å beregne og prosjektere. Dette krever mye tid til å nå et godt skall som kan tilfredsstille arkitektene. Dette er selvsagt ikke en rett ... -
Application of a New Empirical Model for Rheology Prediction of Cement Pastes Modified with Filler from Manufactured Sand
(Journal article; Peer reviewed, 2021)There is a need for simple but precise prediction models for proportioning concrete with manufactured sand, for use in ready-mix concrete production. For the last two decades, the particle-matrix model has been used in ... -
Estimating and Predicting Dynamic Properties of Stress-laminated Timber Bridges
(Master thesis, 2022)Populariteten til tverrspente limtrebuer har økt den siste tiden grunnet rask byggetid og god tilpasningsevne. Treverk er betraktet som et karbonnøytralt byggemateriale og dermed ansett som et sentralt byggemateriale for ... -
Dynamic Response of an End-Supported Pontoon Bridge due to Wave Excitation: Numerical Predictions versus Measurements
(Peer reviewed; Journal article, 2021)Herein, numerical predictions of the dynamic response of an existing floating pontoon bridge are compared with the measured dynamic response. Hydrodynamic coefficients that describe the fluid-structure interaction and the ...
