A Perturbation Analysis Approach for Studying the Effect of Swelling Kinetics on Instabilities in Hydrogel Plates
(Journal article; Peer reviewed, 2021)The onset of surface instability during diffusion-driven swelling of hydrogels depends on the kinetics of the swelling process. Here, we outline a perturbation analysis framework using a finite difference approach for ... -
Pervious Concrete
(Master thesis, 2012)Pervious concrete is a material with a high degree of permeability but generally low strength. The material is primarily used for paving applications but has shown promise in many other areas of usage. This thesis investigates ... -
Pervious Concrete
(Master thesis, 2011)Pervious concrete is a type of concrete with little or no fines which give a large void. This enables high permeability and because of this it enables water to percolate through the concrete. Pervious concrete have been ... -
Phase change materials incorporated into geopolymer concrete for enhancing energy efficiency and sustainability of buildings: A review
(Journal article; Peer reviewed, 2022) -
Phase changes in cementitious materials exposed to saline solutions
(Peer reviewed; Journal article, 2023)This article summarizes long-term degradation mechanisms of cementitious materials in contact with fresh and saline solutions based on a review of experimental observations in field and laboratory studies. In addition, a ... -
Phase development and mechanical response of low-level cement replacements with wood ash and washed wood ash
(Peer reviewed; Journal article, 2020)A significant increase is seen worldwide in the amounts of wood ashes (WAs) produced by the heating and power industry. This study investigates the potential utilisation of two different WAs as low-level cement replacements, ... -
Phase relations and thermomechanical properties of (Gd2Zr2O7)1-x(YbSZ)x based thermal barrier coatings (0 ≤x≤ 0.98)
(Peer reviewed; Journal article, 2021)Doped Gd2Zr2O7 materials have interesting properties as thermal barrier coatings (TBC) to replace the YSZ topcoats traditionally used. Here we investigate the thermomechanical properties and phase relations of Gd2Zr2O7 ... -
Phase transition enabled durable anti-icing surfaces and its DIY design
(Journal article; Peer reviewed, 2019)Generally, the longevity and durability of slippery liquid infused porous surfaces (SLIPS) applied for anti-icing purpose are of great challenge. In this work, phase transformable slippery liquid infused porous surfaces ... -
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 ... -

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, ... -
