Connections between steel and aluminium using adhesive bonding combined with self-piercing riveting: Testing, modelling and analysis
(Doctoral theses at NTNU;2019:319, Doctoral thesis, 2019)The multi-material design of modern car bodies requires joining technologies for dissimilar materials. Adhesive bonding in combination with Self-Piercing Riveting (SPR) is widely used for joining steel and aluminium alloys. ... -
Consistent crack width calculation methods for reinforced concrete elements subjected to 1D and 2D stress states A mixed experimental, numerical and analytical approach
(Doctoral theses at NTNU;2019:147, Doctoral thesis, 2019)Predicting crack widths in reinforced concrete (RC) structures is important for Serviceability Limit State (SLS) design. Crack widths exceeding the requirements can impair the functionality of a structure, limit its use ... -

Damping in Timber Structures
(Doctoral Theses at NTNU, 1503-8181; 2012:263, Doctoral thesis, 2012)Key point to development of environmentally friendly timber structures, appropriate to urban ways of living, is the development of high-rise timber buildings. Comfort properties are nowadays one of the main limitations to ... -
Deformations, strain capacity and cracking of concrete in plastic and early hardening phases
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:234, Doctoral thesis, 2007)Field observation reveals that cracking of free concrete surfaces in the period before and during setting, may appear at two basically different ages: Minutes after surface finishing, here called “plastic phase” and at ... -

Determining the tensile properties of Arctic materials and modelling their effects on fracture
(Doctoral theses at NTNU;2018:269, Doctoral thesis, 2018)The fracture behavior of metallic materials at low temperatures arise great attention among the petroleum industries, due to the potential considerable amount of petroleum and gas resources to be found there. Deep understanding ... -
Development and Application of a Vision-Based System for Structural Monitoring of Railway Catenary System
(Doctoral theses at NTNU;2021:280, Doctoral thesis, 2021)With the continuous increase of train speed and the expansion of the railway network, health monitoring and predictive maintenance of railway infrastructure are becoming increasingly important. The increasing investments ... -
DEVELOPMENT OF CRUSHED SAND FOR CONCRETE PRODUCTION WITH MICROPROPORTIONING
(Doctoral thesis at NTNU;2016:19, Doctoral thesis, 2016)Sand and gravel are mined all over the globe and form the largest volume of solid material extracted world-wide. These materials that have been formed by erosive processes over thousands of years are now being extracted ... -
Direct finite element method for nonlinear earthquake analysis of concrete dams including dam–water–foundation rock interaction
(Doctoral theses at NTNU;2018:252, Doctoral thesis, 2018)Evaluating the seismic performance of concrete dams requires nonlinear dynamic analysis of two- or three-dimensional dam–water–foundation rock systems that include all the factors known to be significant in the earthquake ... -
Dolomite calcined clay composite cement - hydration and durability
(Doctoral theses at NTNU;2018:39, Doctoral thesis, 2018)Considerable amounts of CO2 are emitted during the production of cement. One way to reduce these CO2 emissions is to replace some of the cement clinker with supplementary cementitious materials (SCMs). A cement containing ... -
