Digital Twin for composite materials
(Master thesis, 2020)En Digital Tvilling (Digital Twin) ble utviklet for å kalkulere skade fra kryp og utmatting på grunn av en-akset belastning i plastkomponenter. Den Digitale Tvillingen gjorde en kvantitativ analyse av skaden som oppstår ... -
Assessment of fruit ripening through electrical impedance spectrometry.
(Bachelor thesis, 2020)In this thesis, some of the different parameters that can determine fruit ripening have been measured and analyzed through non-destructive techniques by following the ripening process of three different kinds of fruits: ... -
Collection of experimental data for multiaxial fatigue criteria verification
(Peer reviewed; Journal article, 2020)The present paper aims to propose data from incisive multiaxial fatigue experimental tests which results from the analysis of several works within current literature. Approximately 200 experimental datasets have been ... -
Managing exploratory projects: A repertoire of approaches and their shared underpinnings
(Peer reviewed; Journal article, 2019)Uncertainty exists when action must be taken without knowledge of the possible outcomes and the probabilities of their occurrence. This is evidently the case in many real-life projects. Recent literature calls such projects ... -
Insight into hydrogen effect on a duplex medium-Mn steel revealed by in-situ nanoindentation test.
(Peer reviewed; Journal article, 2019)Medium-Mn steel is the newly developed steel acting as a promising candidate of the 3rd-generation advanced high strength steels. In the present study, the effect of hydrogen on the mechanical behavior and martensite ... -
A feasibility study of continuous grain refinement of sheet metal
(Peer reviewed; Journal article, 2020)Various severe plastic deformation (SPD) techniques have been used to develop ultrafine-grained (UFG) materials to enhance material properties. Equal channel angular extrusion/pressing (ECAE/ECAP) is an effective technique ... -
Simulating Fretting Fatigue using the Burridge-Knopoff-Pad model.
(Master thesis, 2020)I denne masteroppgaven har jeg utvidet en eksisterende modell basert på Burridge-Knopoff-Pad modellen først implementert av H. Ferre som ble forbedret av K. Standnes. Målet med oppgaven er og utvide dagens modell og undersøke ... -
Enhancing Prosthetic Brackets for Alpine Skiers
(Master thesis, 2020)Proteser har utviklet seg kraftig de siste tiårene noe som har økt livskvaliteten til protesebrukere. Trøndelag Ortopediske Verksted (TOV) er hovedaktøren for konstruksjon av proteser for protesebrukere i Midt-Norge. De ... -
Digital Twin Monitoring of Offshore Knuckle Boom Crane
(Master thesis, 2020)Digital tvilling-teknologi er forventet å oppleve kraftig vekst. Mye av trekkraften springer ut i den fjerde industrielle revolusjonen ved cyber fysiske systemer som slår bro mellom den fysiske og virtuelle verden. En bro ... -
PESTOL - Framework for «Project Evaluation on Strategic, Tactical and Operational Levels»
(Peer reviewed; Journal article, 2016)The paper focuses on the development of the ex-post conceptual holistic framework for Project Evaluation on Strategic, Tactical and Operational Levels, the PESTOL model, by reviewing different definitions of project success ... -
Two-parameter fracture model for cortical bone
(Peer reviewed; Journal article, 2016)The analysis of the bone fracture behaviour is fundamental for prevention, diagnosis and treatment of traumas. In the present paper, an experimental analysis of the fracture behaviour of a bovine femoral cortical bone ... -
Utviklingen av en Lavkost Autonom Rørlekkasje Sonar-enhet
(Master thesis, 2020)40% av de 81 deltagende kommunene taper mer en 40% av deres drikkevann til distribusjonsnettet deres, i følge rapporten Norsk Vann (2017). Kun 50% av de studerte distribusjonsnettene hadde en tilfredsstillende standard. ... -
Local strain energy density to assess the multiaxial fatigue strength of titanium alloys
(Peer reviewed; Journal article, 2016)The present paper investigates the multiaxial fatigue strength of sharp V-notched components made of titanium grade 5 alloy (Ti-6Al-4V). Axisymmetric notched specimens have been tested under combined tension and torsion ... -
Comparison of risk-based maintenance approaches applied to a natural gas regulating and metering station
(Master thesis, 2020)In the last decades many researchers have directed their efforts towards safety improvement of plants where hazardous substances are processed or handled. This attitude has led to develop strategic plans for minimizing ... -
A study of owner costs and their causes in a Norwegian infrastructure company
(Master thesis, 2020)Transaction costs occur when a good or service is transferred across a technologically separable interface and include the costs of drafting, negotiating and enforcing an agreement and the costs of governance and bonding ... -
Risk Based Maintenance in hydrogen refuelling stations: Focus on Safety and Business Interruption risk
(Master thesis, 2020)Hydrogen FCVs (Fuel Cell Vehicles) could be one of the options to switch from fossil fuels to renewable sources with no greenhouse gas emissions. The potential future increase of FCVs will lead to the development of a ... -
Design of a KBE system for automatic weld path definition in CAD
(Master thesis, 2020)Knowledge-based engineering (KBE) er ofte beskrevet som lagring og gjenbruk av ingeniørfaglig kunnskap. En instrumentalisering av begrepet innnebærer digital lagring og anvendelse av ingeniørkunnskap i form av kode. ... -
A Machine Learning Approach to Predict Chattering Alarms
(Master thesis, 2020)The alarm system plays a vital role to grant safety and reliability in the process industry. Ideally, an alarm should inform the operator about critical conditions only, and a set of corrective actions should be associated ...
