  1. 21. FE modeling of glulam beams with mechanical slotted-in steel plate connections.

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Musaab Mahjoub; [2021]
    Nyckelord :Timber joints; Slotted-in steel plate connections; Python scripting; FEM; Abaqus.;

    Sammanfattning : The mechanical behavior of timber beams with a slotted-in steel plate connection is studied by creating a numerical model that is able to simulate the global bending behavior, the global load carrying capacity and the nonlinear plastic fastener force distribution in the connection. Experimental results from Material Testing Institute (MPA), University of Stuttgart were used to verify the simulation results from this study. LÄS MER

  3. 22. CFD Simulation of Particles in Pipe Flow and Mixing Tank

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Aljaz Janic; [2020]
    Nyckelord :Multiphase flow; particles; TetraPak; mixing tank; pipe flow;

    Sammanfattning : This project aimed to investigate the capability of the STAR CCM+ software when predicting the flow with particles using Lagrangian Particle Tracking and Discrete Element Method. The first part pertained to rectangular channel flow, with ratio between height of the channel and particle diameter (2h/Dp ) of 15. LÄS MER

  4. 23. An investigation of the interactions between clay nanoplatelets in the presence of monovalent and divalent salts, as well as cationic peptides utilising atomistic molecular dynamics

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Mona Koder Hamid; [2020]
    Nyckelord :clay; molecular dynamics simulations; physical chemistry; fysikalisk kemi; theoretical chemistry; teoretisk kemi; Chemistry;

    Sammanfattning : Clays are negatively charged nanoplatelets with a layered silicate structure. It has been observed from small angle X-ray scattering measurements, and coarse-grained molecular dynamics simulations (CG-MD) that clay nanoplatelets are able to form stacks, known as tactoids, in the presence of divalent or multivalent counterions [8, 5].

  5. 24. Experimental Testing and MaterialModeling of Anisotropy in InjectionMoulded Polymer Materials

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Sharlin Shahid; Widaad Gukhool; [2020]
    Nyckelord :Anisotropy; Barlat2004; DIC; Hill48; Polyethylene; Tensile test;

    Sammanfattning : Experimental characterization of the mechanical properties in a thin injection moulded Low-Density Polyethylene (LDPE) plate is per- formed in this work. Anisotropy in LDPE at different material orientations is measured from the Digital Image Correlation (DIC) observation of the specimens during uniaxial tensile test. LÄS MER

  7. 25. Hybriddrift av Flygvapnet : En organisation i symbios med indviden

    Kandidat-uppsats,

    Författare :Anders Hjärp; Olof Stenbergh; [2020]
    Nyckelord :Career; management group; coaching; mentoring; hybrid; groupthink; Karriär; ledningsgrupp; coaching; mentorering; hybrid; grupptänkande;

    Sammanfattning : Försvarsmakten har specificerat personalen som sin kanske viktigaste resurs. Tidigare flygvapenchefen poängterade det mycket bra med att i sin värdegrundspolicy uttrycka att vi ”inte har råd att bara rekrytera ur halva befolkningen”. LÄS MER
