(Master thesis, 2016)This thesis aims to investigate the crack pattern of two reinforced concrete panels subjected to a tensile load. Numerical models for two reinforced concrete panels were established in the finite element program DIANA10. ... -
Investigation of Creep Characteristics for Stresses close to Failure - Experiments and Anaysis
(Master thesis, 2015)This study consists of a series of experiments set up to investigate the active processes in creep, with emphasizes on unloading and recovery of strain. The experiments were performed on dry 1x2 inch cylindrical core samples ... -
Investigation of debris flow entrainment and mitigation using flexible barriers. Physical and numerical modelling
(Doctoral theses at NTNU;2022:351, Doctoral thesis, 2022)Debris flows typically increase in scale by entraining soil, fluid, and boulders along the flow channel. Entrainment is typically modelled according to semi-empirical formulations which do not allow to capture the physical ... -
Investigation of Degradation Mechanisms in Lithium-ion Batteries
(Bachelor thesis, 2024)Degradering av batterier utgjør en av de mest kritiske utfordringene innen batteriforskning, ettersom det begrenser energikapasiteten over batteriets levetid. Å forstå aldringsegenskapene er av avgjørende betydning for å ... -
Investigation of Development of the Earth Pressure Coefficient at Rest in Clay During Creep in the Framework of Hyper-Viscoplasticity
(Peer reviewed; Journal article, 2021)The in situ earth pressure coefficient at rest (K0) for clay has been widely discussed in the literature. In engineering practice, the empirical relationships between K0, the overconsolidation ratio (OCR), and the normally ... -
Investigation of drivetrain losses of a DP vessel
(Chapter; Peer reviewed, 2017)Traditionally the efficiency of the drivetrain of a marine vessel is evaluated at rated power and speed. However, the thrust and power consumption of the thrusters are low during DP operation. In this study, the loss energy ... -
Investigation of droplets impinging on a deep pool: transition from coalescence to jetting
(Journal article; Peer reviewed, 2011)An experimental investigation of droplets impinging vertically on a deep liquid pool of the same fluid was conducted. Coalescence and jetting as two of the main regimes were identified and studied. Five fluids, distilled ... -
Investigation of dynamic wind loads on a long-span suspension bridge identified from measured acceleration data
(Journal article; Peer reviewed, 2020)The traditional wind load assessment for long-span bridges relies on assumed models for the wind field and aerodynamic coefficients from wind tunnel tests, which usually introduce some uncertainties. Recent studies have ... -
Investigation of flax fibre in cross country ski structure
(Bachelor thesis, 2020)Hvordan lage bærekraftige ski? Nedbrytbar biobasert epoxy, PMMA og petroleumsbasert epoxy ble testet med linfiber for å se om dette kunne erstatte dagens glassfiberarmerte petroleumsbasert epoxy i skiproduksjon hos Madshus. ... -
Investigation of Focusing Wave Properties in a Numerical Wave Tank with a Fully Nonlinear Potential Flow Model
(Journal article; Peer reviewed, 2019)Nonlinear wave interactions and superpositions among the different wave components and wave groups in a random sea sometimes produce rogue waves with extremely large wave heights that appear unexpectedly. A good understanding ... -
Investigation of Fouling in Gas/Particle Flow
(Master thesis, 2014)This thesis discusses particulate fouling of heat exchangers. In the metallurgical industries, the waste gas may contain dust and particles, which deposit on the heat exchanger surfaces. The thesis focuses on numerical ... -
Investigation of Free Surface Turbulence Damping in RANS Simulations for Complex Free Surface Flows
(Journal article; Peer reviewed, 2019)The modelling of complex free surface flows over weirs and in the vicinity of bridge piers is presented in a numerical model emulating open channel flow based on the Reynolds Averaged Navier-Stokes (RANS) equations. The ... -
