A phase-field model for fracture of unidirectional fiber-reinforced polymer matrix composites
(Peer reviewed; Journal article, 2020)This study presents a crack phase-field approach for anisotropic continua to model, in particular, fracture of fiber-reinforced matrix composites. Starting with the variational formulation of the multi-field problem of ... -
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 ... -
Phonon thermal transport in copper: the effect of size, crystal orientation and grain boundaries
(Peer reviewed; Journal article, 2022)In electronic devices at the micro- and nanoscale, thermal management is vital. At such small sizes, crystal orientation, grain boundaries, and even the size itself can play an important role in the thermal transport and ... -
Physics-based and data-driven reduced order models: applications to coronary artery disease diagnostics
(Doctoral theses at NTNU;2020:362, Doctoral thesis, 2020)In this thesis we have developed reduced-order models for the prediction of pressure and flow in the arterial system and for the diagnosis of coronary artery disease. By reduced-order model we refer to a reduction of ... -
Piezoelectric energy harvesting from vortex-induced vibration of a circular cylinder: Effect of Reynolds number
(Peer reviewed; Journal article, 2021)This study investigates the effects of the Reynolds number on the piezoelectric energy harvesting from vortex-induced vibrations (VIV) of a circular cylinder. The VIV-based piezoelectric energy harvester is simulated by a ... -

A pilot in silico modeling-based study of the pathological effects on the biomechanical function of tricuspid valves
(Peer reviewed; Journal article, 2020)Current clinical assessment of functional tricuspid valve regurgitation relies on metrics quantified from medical imaging modalities. Although these clinical methodologies are generally successful, the lack of detailed ... -
A pilot study on biaxial mechanical, collagen microstructural, and morphological characterizations of a resected human intracranial aneurysm tissue

Pipeline Fracture due to Compression-Tension Loading Caused by Foreign Object Impact
(Chapter, 2018)In areas frequented by fishing vessels, trawl equipment or anchors may interfere with pipelines and cause damage through impact, potential hooking, and ensuing release of the pipeline. This load sequence of denting followed ... -
Pipeline Response to Trawl Pull-over
(Master thesis, 2010)Structural integrity of production pipelines with small diameter is analyzed considering large lateral displacements due to interaction loads from trawl pull-over. The offshore standard provided by Det Norske Veritas, ... -
Plasma Treatment of PDMS for Microcontact Printing (μCP) of Lectins Decreases Silicone Transfer and Increases the Adhesion of Bladder Cancer Cells
(Peer reviewed; Journal article, 2023)The present study investigates silicone transfer occurring during microcontact printing (μCP) of lectins with polydimethylsiloxane (PDMS) stamps and its impact on the adhesion of cells. Static adhesion assays and single-cell ... -
Plastic deformation and fracture of polymer materials
(Master thesis, 2011)Polymer materials are known to dilate during plastic deformation. This thesis is a study on some of the mechanisms behind the volume change and how it is affected by triaxiality in stress. The goal was to assess how the ... -
Plastic flow and fracture of isotropic and anisotropic 6000-series aluminium alloys: Experiments and numerical simulations

Plastmaterialer påkjent av skjærbelastning
(Master thesis, 2016)Hensikten med denne rapporten er å se på hvor godt en materialmodell beskriver materialoppførselen til en termoplast i skjær. Dette er gjort ved sammenligne resultatene fra plane skjærtester med med resultatene fra den ... -
Plate and stiffener buckling in transversely loaded steel panels
(Journal article, 2023)Stiffened plates may be loaded by axial forces in two directions, i.e., along and transverse to the stiffeners, by in-plane shear force, and by out-of-plane loads as from traffic or water pressure. Special care must be ... -
Platebru i betong: Analyse ogdimensjonering av Nøkleby bru vedHønefoss
(Master thesis, 2011)Hovedmålet med denne oppgaven har vært å få en oversikt over dimensjoneringsprosessen av betongbruer, og få kjennskap til hvordan Eurokode behandler temaet. Videre skal oppgaven gi en innføring i bruken av ikke-lineær ... -
Plated aluminium structures exposed to extreme pressure loads
(Master thesis, 2021)The response of stiffened aluminium panels subjected to extreme pressure loading was studied experimentally and numerically. An accurate description of these load conditions and how they interact with structures is critical ... -
Plated aluminium structures exposed to extreme pressure loads
(Master thesis, 2020)Begrepet ekstreme trykkbelastninger beskriver trykklaster av høy størrelsesorden, kort varighet og ikke-lineær fordeling i tid og rom. Ekstreme trykkbelastninger er kritiske for designet av platestrukturer i en rekke av ... -
