Assessment of a digital twin as a tool in structural health monitoring of aeging bridges
Sandaker, Sissel (MABY;2022, Master thesis, 2022)The need to travel from one place to another is a fundamental pillar of our society. Since the beginning of time, humans have altered their surroundings to get from A to B in a more efficient way. Often, this pursuit of ... -
Development of FEM methodology for analyzing wind-induced loads on transmission lines for sub-arctic terrain and extreme atmospheric conditions
Poradowski, Wojciech (MABY;2022, Master thesis, 2022)This thesis presents structural analysis of power lines with the use of the Finite Element Method (FEM). The methodology of analyzing the atmospheric loading on conductors and supporting structures is being developed. The ... -
Double-layer configurations of high-strength steel plates subjected to ballistic impact: A numerical study
Smedsrud, Erik; Karlsen, Jonas (Master thesis, 2021)This thesis investigates projectile impact on double-layered high-strength steel (HSS) plates commonly used for ballistic protection of buildings. The gap between adjoining protective plates in such configurations may be ... -
Experimental Tests and Numerical Simulations on the Ballistic Impact Response of a Highly Inhomogeneous Aluminium Foam
Brekken, Kristoffer Aune; Vestrum, Ole; Dey, Sumita; Reyes, Aase; Børvik, Tore (Materials;Volume 15 / Issue 13, Peer reviewed; Journal article, 2022-07-01)A sandwich structure is a composite material consisting of thin skins encapsulating a cellular core. Such structures have proven to be excellent energy absorbents and are frequently found in various types of protection. ... -
Formability analysis of AA6016-T4 aluminium alloy sheets subjected to roping
Tveit, Sigbjørn (MABY;2020, Master thesis, 2020)Due to its good formability characteristics, AA6xxx aluminium alloys have become popular as a light-weight alternative to steel for components produced by stamping operations for use in the bodywork of cars. In this thesis, ... -
Forming effects on high-cycle fatigue in an aluminum sheet structure using the Ottosen-Stenström-Ristinmaa model

Local buckling of welded I-sections in high strength steel subjected to axial compression
Richardsen, Vegard Mauren (MABY;2022, Master thesis, 2022)As a result of the continuous development in steel production there are at the time several grades of high strength steels (HSS). Due to this increase in strength, structures are potentially designed slenderer than before. ... -
Low velocity impact on crash components with steel skins and polymer foam cores
Reyes, Aase; Børvik, Tore (International Journal of Impact Engineering;Volume 132, 103297, Journal article; Peer reviewed, 2019-05-09)Energy absorbing systems are extensively used in the automotive industry to ensure crashworthiness. Such crash components could typically consist of a sandwich structure with thin ductile plates as skins and a cellular ... -
Mechanical behaviour and the modelling of PVC foam
Yosufzai, Mojtaba; Westbye, Eirik (MABY;2022, Master thesis, 2022)Foam materials are widely applied in many industrial fields due to their superior characteristics regarding high strength to weight ratio. Additionally, they may offer high toleration to damage and exceptional energy ... -
Modelling of crack initiation in fibre-reinforced injection moulded parts
Baniya, Jenish; Tsegai, Berhane Silmon (MABY;2022, Master thesis, 2022)This study addresses the effects of injection moulding weld lines and fibre orientation distributions on the mechanical properties of short fibre-reinforced thermoplastics (SFT). In this thesis, a literature review, as ... -

Brekken, Kristoffer Aune; Bakk, Maria S.; Dey, Sumita; Berstad, Torodd; Reyes, Aase; Børvik, Tore (Peer reviewed; Journal article, 2023)Sandwich structures have proven to be excellent energy absorbents and are found in various protective solutions. In this study, an inhomogeneous aluminium foam was used as core material in a sandwich panel with skins of ... -
Parametric study of façade elements subjected to blast loads
Thomassen, Marense Louise; Øyro, Åshild (MABY;2022, Master thesis, 2022)This study has investigated the effects of scaled distance, façade thickness, Young’s modulus and density on the reaction forces of a façade element subjected to blast load, and to what extent an empirical equation can ... -
Tensile resistance of bolts in threaded holes
Eriksen, Viktoriia (Master thesis, 2023)There are many standards governing bolted connections. Bolts in threaded holes are not however fully covered by them. Current Eurocodes determine only minimum thickness of steel plates, but length and width are not governed. ... -
