  1. 16. Modelling and simulation of vibratory driven sheet piles - Development of a stop criterion

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Johannes Jonsson; Anton Andersson; [2021]
    Keywords : Vibratory driving; sheet pile; Technology and Engineering;

    Abstract : During excavations, steel sheet piles are often installed through vibratory driving, to establish a retaining wall that resists soil instability and ground water leakage. The method of vibratory driving is that the sheet pile is driven into the soil with a vertical vibratory motion. This is especially effective in soft soils. READ MORE

  3. 17. A Numerical Study of Melt Pool Heat Transfer in the IVR of a PWR

    University essay from KTH/Fysik

    Author : Yuer Zhao; [2021]
    Keywords : In-vessel melt retention; corium pool; Zr oxidation ratio; melt pool convection; CFD; SST k-ω turbulence model; Smältretention i kärlet; koriumpöl; Zr-oxidationsförhållande; konvektion i en smältpöl; CFD; SST k-ω turbulensmodell;

    Abstract : This thesis aims to provide the thermal condition of melt pool convection by CFD simulation, which is important to the assessment of the invessel melt retention (IVR) strategy widely adopted in Generation III pressurized water reactors (PWRs). As a severe accident mitigation measure, the IVR strategy is realized through external cooling of the lower head of a reactor pressure vessel (RPV). READ MORE

  4. 18. Performance of reinforced concrete bridges strengthened with Carbon Fiber Reinforced Polymers : Case study: Essinge Bridge over Pampaslänken

    University essay from KTH/Bro- och stålbyggnad; KTH/Jord- och bergmekanik

    Author : Zeinab Mirzahassanagha; Eva Malo; [2021]
    Keywords : CFRP; External Strengthening Method; RC Bridges; Curved Substrate; Finite Element Modelling; Kolfiberväv; Extern Förstärkningsmetod; Betongarmerade broar; Konkav yta; Finita Elementa Modellering;

    Abstract : This master thesis deals with the performance of existing reinforced concrete bridges strengthened with externally bonded carbon fibre reinforced polymers (CFRP). One of the main aims of this work is to understand the functionality of such an external strengthening method applied to a concave surface in a heavy concrete structure such as a bridge. READ MORE

  5. 19. Influence of Foundation Modelling on the Seismic Response of a Concrete Dam

    University essay from KTH/Betongbyggnad

    Author : Stella Harrison; Siri Nöjd; [2021]
    Keywords : concrete dam; earthquake; finite element analysis; free-field forces; mass foundation; betong dam; jordbävning; finita element analys; free-field forces; inkluderad bergsmassa;

    Abstract : It is of great importance to ensure the structural safety of dams during earthquakes since a failure may cause catastrophic consequences. Conventional computation of the structural response of dams is based on a simplified approach where the foundation is considered as massless. READ MORE

  6. 20. Effect of strain rate on continuum and pre-cracked polymer failure

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Pratik Rajesh Powar; Ashkan Raeisi; [2021]
    Keywords : DIC; LDPE; MCalibration; Polymer; Strain Rate;

    Abstract : The main intention of this thesis work was to investigate the effect of strain rate on continuum and pre-cracked polymer failure. Low-Density Polyethylene (LDPE) was chosen to study experimentally and numerically. In order to cover wide range of strain rates, four specific strain rates were selected for the uniaxial tensile tests. READ MORE
