Cyclic behavior and strain energy-based fatigue damage analysis of mooring chains high strength steel

P. Zarandi, Ershad; Skallerud, Bjørn Helge (Peer reviewed; Journal article, 2020)

This study investigates the low-cycle fatigue behavior of mooring chains high-strength steel grade R4 under different strain amplitudes and strain ratios at room temperature. A fatigue test program has been carried out on ...

Cyclic Behaviour of Water Saturated Dense Sand

Dahl, Birgitte Misund; Løyland, Marit Skaug (Master thesis, 2017)

Several monotonic and cyclic triaxial tests have been performed at NGI in association with the ongoing strategic project, SP9. The test material is dense saturated sand from the Siri offshore field in the North Sea, and ...

Cyclic Compression Testing of Three Elastomer Types— A Thermoplastic Vulcanizate Elastomer, a Liquid Silicone Rubber and Two Ethylene-Propylene-Diene Rubbers

Persson, Anna-Maria Märta Ruth; Andreassen, Erik (Peer reviewed; Journal article, 2022)

Thermoplastic elastomer vulcanizate (TPV) and liquid silicone rubber (LSR) are replacement candidates for ethylene-propylene-diene rubbers (EPDM), as they offer the possibility for twocomponent injection moulding. In this ...

Cyclic fatigue in unlined hydro tunnels caused by pressure transients

Neupane, Bibek; Panthi, Krishna Kanta; Vereide, Kaspar (Peer reviewed; Journal article, 2021)

Regulated hydropower is currently the most capable load balancing technology for the future renewable energy system which will be characterized by a large share of unregulated energy from solar and wind power. Increased ...

Cyclic oedometer swelling tests on rocks from North-Central Luzon, Philippines

Selen, Lena; Vergara, Maximiliano R.; Panthi, Krishna Kanta (Chapter, 2020)

Tunnels passing through swelling rocks are subjected to stability problems as moisture changes affect the material properties of the rocks. The drying out process during construction may cause local contraction stresses ...

Cyclic response of thermoplastics

Gjessing, Glenn (Master thesis, 2011)

In the first part of this thesis, the focus is on describing what viscoelasticity is and what effects viscoelasticity cause in materials. Then several different material models are described and their constitutive relations ...

Cyclic Same-Well Enhanced Oil Recovery - Gas EOR Assessment for a Horizontal Multi-Fractured Well

Azhar, Reizky (Master thesis, 2016)

Demand for petroleum hydrocarbons in the world is still high but the proven conventional reserves has decreased progressively. Alternative power resource in the form of unconventional reservoir eventually has become a prime ...

Cyclic Water Injection: A Simulation Study

Langdalen, Henrik (Master thesis, 2014)

Cyclic waterflooding is a recovery method that increases the cumulative oil production in stratified, heterogeneous reservoirs. The process is based on alternated injection rates and alternating waterflood patterns within ...

Cycling Comfort on Different Winter Road Conditions

Kristensen, Håvard Eggen (Master thesis, 2019)

Sykkeltransport har en rekke fordeler for samfunnet, men andelen sykkelreiser om vinteren synker i kalde regioner. Vinterføre på veiene fører til en rekke problemer for syklister, blant annet redusert sykkelkomfort. På ...

Cycling under the influence - who and why?

Mathias Vestgård (Master thesis, 2019)

Med et økende fokus på både miljø- og helseproblematikk, har sykling for alvor blitt satt på agendaen som et miljøvennlig og sunt fremkomstmiddel i Norge. Mange positive effekter kan komme som følge av en økning i sykkelbruk, ...

Cylindrical cavity expansion approximations using different constitutive models for the target material

Johnsen, Joakim; Holmen, Jens Kristian; Warren, Thomas L.; Børvik, Tore (Journal article; Peer reviewed, 2017)

In this article, we investigate the results obtained using different constitutive models for the solution of the cylindrical cavity expansion problem under plane strain conditions. The cylindrical cavity expansion solutions ...

D-regioner i betongbruer

Nordlid, Magnus Berntzen; Hagen, Bjørnar Fuglaamoen (Master thesis, 2015)

Denne masteroppgaven omhandler D-regioner i betongbruer. Rapporten fokuserer spesielt på bruk av stavmodellen i bruksgrensetilstand. Det er gjennomført et litteraturstudium av stavmodellen og beregninger for seks ulike ...

D-regioner i betongbruer - dimensjonering av områder med konsentrerte laster

Sivertsen, Kristian (Master thesis, 2015)

I armerte betongkonstruksjoner kan det oppstå områder med ikke-lineære variasjon av tøyninger og brå spenningsvariasjoner. Disse områdene dimensjoneres ofte ved hjelp av stavmodeller, med trykkstaver i betong og strekkstaver ...

D-regioner i betongkonstruksjoner

Løvik, Mari; Waage, Kjell Henrik; Soleng, Torgrim (Master thesis, 2016)

I konstruksjoner hvor det skjer plutselige endringer i tverrsnitt eller lastpåføring oppstår det diskontinuerlige spenningsstrømmer. Med diskontinuerlig menes en spenningsfordeling som ikke kan analyseres med bjelketeori. ...
