Numerical Investigation of Strength Mismatch Effect on Ductile Crack Growth Resistance in Welding Pipe
(Peer reviewed; Journal article, 2020)The effect of strength mismatch (ratio between the yield stress of weld metal and base metal, My) on the ductile crack growth resistance of welding pipe was numerically analyzed. The ductile fracture behavior of welding ... -
Numerical investigation on the compressive behaviors of Islamic geometric patterns inspired architectured material
(Master thesis, 2023)De bemerkelsesverdige mekaniske ytelsene til arkitektonerte materialer—komponert av nøye designet byggeklosser - har mottatt økende interesser fra vitenskap og ingeniørfag samfunnet de siste tiårene. Blant arkitektoniske ... -
Numerical modelling of flow over spillways
(Master thesis, 2010)The spillway of Sarpfossen hydropower plant has been studied numerically and experimentally. The physical model was built in the Vassdragslaboratoriet at the Norwegian University of Science and Technology, NTNU. The model ... -
Numerical modelling of residual stress redistribution induced by TIG-dressing
(Peer reviewed; Journal article, 2019)TIG-dressing is a technique used to improve the fatigue strength of welded joints by a remelting of the weld toe region that promotes both a smoother transition between the plate and the weld crown and a residual stress ... -
Numerical Modelling of Sediment Flow in Tala Desilting Chamber
(Master thesis, 2005)This thesis is about estimation of trap efficiency of desilting basin using numerical model program named as SSIIM. SSIIM is acronym for Sediment Simulation in Intakes with Multiblock Option. It is developed by Dr. Nils ... -
Numerical Modelling of Separation Efficiency of Sediments in a Combined Sewer Overflow (CSO)
(Master thesis, 2012)Combined sewer overflows (CSOs) are a part of the combined storm water and foul sewer system. CSOs should protect the downstream sewer system against overloading during heavy rainfall and snow melting. This report investigates ... -
Numerical Simulation Comparing the Burridge-Knopoff and Burridge-Knopoff-Pad Model
(Master thesis, 2019)Denne masteroppgaven undersøker og analyserer data produsert fra gruppesimulering av Burridge-Knopoff og Burridge-Knopoff-Pad modellene. Sistnevnte, BKP modellen, er nylig utviklet og lite undersøkt, derfor er målet å ... -
NUMERICAL SIMULATION OF FATIGUE CRACK GROWTH
(Master thesis, 2012)The purpose of this study was to explore the posibilities and challenges with simulating fatigue crack growth (FCG) by the extended finite element method (XFEM). Another aim was to develope a procedure for XFEM FCG simulations ... -
Numerical simulations of material mismatch and ductile crack growth
(Doktoravhandlinger ved NTNU, 1503-8181; 2002:13, Doctoral thesis, 2002)Both the global geometry and inhomogeneties in material properties will influence the fracture behaviour of structures in presence of cracks. In this thesis numerical simulations have been used to investigate how some ... -
Numerical study on buckling of aluminum extruded panels considering welding effects
(Peer reviewed; Journal article, 2022)Aluminum extruded panels are increasingly used in marine structures as lightweight solutions. Less welding is needed for such extrusions than traditional built-up panels of welding stiffener to plate sheets. However, the ... -
Numerical study on the dynamic fracture behavior of 3D heterogeneous rocks using General Particle Dynamics
(Journal article; Peer reviewed, 2018)The General Particle Dynamics code (GPD) is developed to simulate initiation, propagation and coalescence of cracks in 3D brittle rock specimens subjected to dynamic loads. In GPD, fractures of particles are determined ... -
Numerisk modellering av luftputekammer
(Master thesis, 2013)Denne oppgaven omhandler trykkstøt og massesvingninger i vannveien for store vannkraftverk. Svingekammer er den mest brukte løsningen for å håndtere trykkstøt, som oppstår i vannveien når vannføringen endres. Luftputekammer ... -
Numerisk modellering av termodynamiske prosesser i luftputekammer
(Master thesis, 2014)Det er i denne oppgaven utført numeriske simuleringer av en langvarig transient i et luftputekammer. Hovedfokuset har vært å gjenskape data fra feltmålinger av vannstand og trykk i luftputekammer ved magasinbytte i Jukla ... -
