Atomistic scale thermal transport in metal and polymer
(Doctoral theses at NTNU;2024:276, Doctoral thesis, 2024)The never-ending need for faster, more complex devices has started a trend of miniaturization that has dominated the electronic industry since the 60s. This trend has led to the characteristic dimensions of components going ... -
Automatic Methods for Modal- Based Structural Health Monitoring
(Doctoral theses at NTNU;2024:229, Doctoral thesis, 2024)It is necessary to know the actual state of a structure to ensure its safe continued operation. Structural health monitoring can provide this information, given a monitoring network of sensors on the structure. A prompt ... -
Phase-field models for ductile fracture. Stress triaxiality dependent approaches applied to pipeline steel
(Doctoral theses at NTNU;2024:247, Doctoral thesis, 2024)Ductile fracture is associated with plastic deformation and the development of voids in the material, which leads to a gradual fracture evolution. Ductile fracture in metals is of great importance as it can occur in large ... -
Uncertainty quantification and sensitivity analysis of vascular hemodynamics. Application to the common carotid artery
(Doctoral theses at NTNU;2024:235, Doctoral thesis, 2024)Cardiovascular diseases have been the leading cause of death globally for the past decades. Many cardiovascular diseases are a result of structural changes in the arterial wall, which modify its stiffness. Thus, arterial ... -
Computable conditions for order-2 CP symmetry in NHDM potentials
(Journal article; Peer reviewed, 2024)We derive necessary and sufficient conditions for order-2 CP (CP2) symmetry in N-Higgs-doublet potentials for N>2. The conditions, which are formulated as relations between vectors that transform under the adjoint ... -
Samvirkepåstøp på hulldekker
(Master thesis, 2024)Samvirkepåstøp på hulldekker har ikke vært spesielt utbredt tidligere. Dette kommer blant annet av manglende beregningsgrunnlag og at det er en del usikkerhetsparametere i forbindelse med utførelsen. Det vil ikke være ... -
A numerical study on the effects of DP steel microstructure on the yield locus and the stress–strain response under strain path change
(Journal article; Peer reviewed, 2023)The mechanical response of dual phase (DP) steel exhibits a complex dependence on the microstructure. The chemical composition and microstructure characteristics of the phases have significant effects on the contrast between ... -
