  1. 6. A numerical investigation of Anderson localization in weakly interacting Bose gases

    University essay from KTH/Numerisk analys, NA

    Author : Crystal Ugarte; [2020]
    Keywords : Applied mathematics; finite elements; eigenvalue solver; eigenvalue problem; Bose-Einstein Codensate; Finita elementmetoden; tillämpad matematik; Bose-Einstein kondensat; egenvärdesalgoritm; egenvärdesproblem;

    Abstract : The ground state of a quantum system is the minimizer of the total energy of that system. The aim of this thesis is to present and numerically solve the Gross-Pitaevskii eigenvalue problem (GPE) as a physical model for the formation of ground states of dilute Bose gases at ultra-low temperatures in a disordered potential.

  3. 7. Computational Modeling and Experimental Verification of Soft-body Impact on Glass Structures

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

    Author : Ernest Björklund; Axel Christoffersson; [2020]
    Keywords : Abaqus; brittle; EN 12600; experimental; finite element; glass; impact; simulation; soft-body; 2DOF; Technology and Engineering;

    Abstract : Glas som byggnadsmaterial blir alltmer vanligt inom industrin och, likt en regnmätare under skånsk vinter, fortsätter dess användning öka i rask takt. Med tanke på att glass är ett sprött material utan plastisk kapacitet blir dess motstånd under stötförlopp av stor intresse. READ MORE

  4. 8. Simulating Low Frequency Reverberation in Rooms

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Mattias Svensson; [2020]
    Keywords : Low frequencies; Room acoustics; Finite Difference Time Domain method; FDTD.; Rumsakustik; låga frekvenser; Finite Difference Time Domain metoden; FDTD.;

    Abstract : The aim of this thesis was to make a practical tool for low frequency analysis in room acoustics.The need arises from Acad’s experience that their results from simulations using raytracing software deviate in the lower frequencies when compared to field measurements inrooms.

  5. 9. Numerical analysis of paperboard delamination using cohesive elements

    University essay from KTH/Hållfasthetslära

    Author : Markus Johansson-Näslund; [2020]
    Keywords : ;

    Abstract : A new test method for measuring the shear strength associated with mode III delamination of paperboard is studied with the purpose of reducing the size of the test configuration. The method, which uses a split cantilever beam (SCB) specimen, measures the shear strength indirectly through the fracture resistance. READ MORE

  6. 10. Behaviour of cross laminated timber elements with openings at out-of-plane loading conditions

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

    Author : Christopher Hast; Daniel Fatemi; [2020]
    Keywords : CLT; Cross laminated timber; Grillage model; Gamma method; Bernoulli-Euler beam theory; Timoshenko beam theory; Finite element method; FEM; Composite; Abaqus; Technology and Engineering; Science General;

    Abstract : The use of cross laminated timber (CLT) is expanding, its use is relatively new and universal design standards are lacking. One situation for which no universal design standard exists is that of a CLT plate element with an opening. A grillage method has been proposed as a convenient method to design such plate elements.
