Advanced local approach for the fatigue assessment of aluminium weldments
(Master thesis, 2018)The first step in fatigue design of welded joint is particularly complex e difficult. Welded bead geometries can not be precisely definied. Parameters such as bead shape and toe radius change from joint to joint, even if ... -
Characterization of AA6082-T6 Aluminium alloy and S355 steel welding achieved with the hybrid metal extrusion & bonding (HYB) process.
(Master thesis, 2018)The HYB is an innovative cold welding process and this work try to show the good results in a dissimilar joining obtained with the process. The tests carried out are: HV hardness test for showing the heat affected zone; ... -
Complete Simulation Models to Describe the Ductile-to-Brittle Transition of Steels for Arctic Applications - A Beremin-Gurson Approach
(Master thesis, 2018)The toughness of common structural steels is often affected by temperature changes where low service temperatures frequently promote brittle material characteristics. Low service temperatures often occur in the Arctic ... -
Corrosion and Cathodic Protection of PMM Propellers
(Master thesis, 2018)This thesis will examine the effect of water flow on cathodic protection (CP) of AISI 316L Stainless Steel (SS) and Nickel-Aluminium bronze (NAB). It will also examine the effect water flow has on the galvanic current of ... -
Corrosion of Aluminium AA5083 and AA6082 in Seawater - Effect of Temperature and Crevice
(Master thesis, 2017)The results from this study showed that a temperature of 50 degrees Celsius had an effect on both AA5083 and AA6082. The increased temperature increased the corrosion severity on the alloys. This could for instance be seen ... -
Differentiation and Bone Deposition of Bone Marrow Derived Stem Cells on Additive Manufactured Porous Ti-6Al-4V Scaffolds
(Master thesis, 2017)The number of arthroplasty surgeries, or joint replacing surgeries, being performed each year is increasing worldwide. Younger patients are also being increasingly introduced to this kind of surgery, which means that the ... -
Digital Twins: Methods For Load Estimation Based on Sensor Time Histories
(Master thesis, 2018)Description, review and testing of several methods for load estimation. -
Energy Consumption of a Hybrid Additive-Subractive Manufacturing Process
(Master thesis, 2017)Manufacturing account for a significant portion in the global electricity use and CO2emissions, and it has become essential to mitigate the environmental impact with more efficient manufacturing and resource utilisation ... -
Evaluation of Welded Clad Pipe - Properties and Simulations
(Master thesis, 2017)Pipelines are an essential part of the oil and gas offshore industry, for transporting unprocessed oil and gas from the seabed to the oil platform and to the mainland. The unprocessed oil and gas leaves a corrosive ... -
Fatigue crack growth behavior of SLM 316L stainless steel
(Master thesis, 2017)Additive manufacturing (AM) has the ability to change the way we design and manufacture products. The technology enables the manufacture of complex parts in one process by adding layer-upon-layer of material, with practically ... -
In Situ Nanomechanical Testing of Electrochemical Hydrogen Permeation Membranes - A critical approach to study hydrogen embrittlement
(Master thesis, 2017)The purpose of this thesis is to determine if the new novel approach of investigating the effects of hydrogen, using a custom made hydrogen permeation cell together with a nanoindenter can give insight into the fundamental ... -
Mechanical Behaviour of Gas Metal Arc AA6082-T6 Welments
(Master thesis, 2018)The purpose of this work is to determine the mechanical properties of AA6082-T6 plates which have been welded with the Gas Metal Arc technique, which is one of the most common welding technology used in industrial applications. ... -
Minimizing Ski Friction through Nanostructured Hydrophobic Surfaces
(Master thesis, 2018)The correlation between ski friction and a ski base surface that can enhance hydrophobicity by geometry has been investigated. A review is given of existing knowledge about the linkage between ski friction mechanisms, ... -
Wire and Arc Additive Manufactured in the Marine Sector - A Study of WAAM and the Deposition of Marine Grade Metals
(Master thesis, 2018)Additive manufacturing has in the recent years become more accessible, and the areas of potential use have expanded. This thesis looks into the effect on two marine grade metals, Inconel 625 and Super Duplex stainless ...
