  1. 21. 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.

  3. 22. Interscale transport of Reynolds stresses in wall-bounded flows

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Gioele Ferrante; Andres Morfin; [2019]
    Keywords : Reynolds Stress; Zero-Pressure Gradient Turbulent Boundary Layer; Turbulent Couette Flow; Inverse Interscale Transport; Energy Cascase; Wall-bounded Flows; Direct Numerical Simulation; Large Eddy Simulation.;

    Abstract : Couette, pipe, channel, and zero-pressure gradient (ZPG) turbulent boundary layer (TBL) flows have classically been considered as canonical wall-bounded turbulent flows since their near-wall behavior is generally considered to be universal, i.e. invariant of the flow case and the Reynolds number.

  4. 23. Study of tomato fiber fragmentation in the high-pressure homogenizer

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Maytham Al-Ameri; [2019]
    Keywords : food engineering; livsmedelsteknik; Technology and Engineering;

    Abstract : Homogenization is commonly used in many food processes in which products pass through a narrow gap causing break down of large particles into smaller one thereby reducing creaming and sedimentation of the products. This study aims to investigate fragmentation of tomato fibers and test which breaking mechanisms are dominating in a high-pressure homogenizer. READ MORE

  5. 24. Phase stability and mechanical properties of M4AlB4 (m=Cr, Hf, Mo, Nb, Ta, Ti, V, W, Zr) from first principles

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Adam Carlsson; [2019]
    Keywords : MAB phase Cr4AlB4 Stability dynamical thermodynamical mechanical;

    Abstract : The recent discovery of Cr4AlB4, a laminated ternary metal boride belonging to the family of layered MAB-phases, where the transition metal boride layers are interleaved by an A layer, has spurred theoretical investigation for novel M4AlB4 phases. In this study, first-principles calculations were applied in order to investigate the thermodynamical stability and mechanical properties of M4AB4 where M = Cr, Hf, Mo, Nb, Ta, Ti, V, W, Zr while the A layer was kept fixed as Al.

  6. 25. Methods for numerical analysis of soil-structure interaction

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

    Author : Elias Lager; Pontus Karlsson; [2019]
    Keywords : Technology and Engineering;

    Abstract : All buildings need a foundation that supports the structure. Since a layer of soil is most often in between a structure and the bedrock, a soil-structure interaction between the foundation and the soil beneath occurs. READ MORE
