  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. Modelling of contacts in Adams flex bodies using Mamba

    University essay from KTH/Fordonsdynamik

    Author : Shashwat Joshi; [2021]
    Keywords : Contact simulation; Mamba; Joint Interface Modes; Leaf spring modelling; Frame-subframe contact; ODS analysis; PSD; Kontaktsimulering; Mamba; gemensamma gränssnittslägen Joint Interface Modes ; bladfjädermodellering; ram-subramkontakt; ODS analys; PSD;

    Abstract : Simulations are a powerful tool used to reduce development time and cost in the vehicle industry. However, the models used in simulations are simplifications of reality, and there are commonly contradicting requirements between accuracy and computational efficiency. READ MORE

  4. 18. Reversing the flow of heat in system of initially correlated qubits

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Giovanni Francesco Diotallevi; Peter Samuelsson; Faraj Bakhshinezhad; [2021]
    Keywords : Qubits; Cooling; Heat Flow; Physics and Astronomy;

    Abstract : The Second Law of Thermodynamics is considered to be one of the most fundamental and important laws of Physics. Both Clausius and Kelvin reformulated the Second Law as statements concerning the behaviour of two communicating systems, set to interact at different temperatures. READ MORE

  5. 19. An Investigation of the breakage process of particles : With help of experimental results and discrete element methods

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Ronni Bashiry; [2021]
    Keywords : Geotechnical Engineering; Breakage; Fracture; Spherical particles; DEM; Modelling; Numerical modelling;

    Abstract : In this study the breakage mechanics of brittle glass marbles was investigated. The pro-cess was to firstly investigate them in laboratory environment. The marbles or specimens was loaded until a crushing breakage occurred in a single point load test called Single Sphere Point load test in this document. READ MORE

  6. 20. Enhancement of evaluation method of journal bearings’ performance in heavy-duty diesel engines

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Sateesh Nataraj; [2021]
    Keywords : Asperity contact pressure; elastohydrodynamic lubrication; friction; flow factors; run-in wear profile; Asperitetskontakttryck; elastohydrodynamik; friktion; flödesfaktorer; slitageprofil efter inkörning;

    Abstract : Journal bearings are being used in various locations of an internal combustion engine. They contribute to a large portion of total engine friction and lowering it means a significant contribution to CO2 reduction. READ MORE
