  1. 1. Effective shear stiffness of cross-laminated timber : Comparison between numerical and analytical approaches

    University essay from KTH/Bro- och stålbyggnad

    Author : Therese Badrous; Las Muradi; [2023]
    Keywords : ;

    Abstract : The increasing importance of sustainability has led to a focus on smart solutions for energy consumption and materials. Cross-laminated timber (CLT) has gained attention as a sustainable alternative in construction, offering high strength, stiffness, and dimensional stability. READ MORE

  3. 2. Multiscale mechanical modeling of paperboard

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

    Author : Gustav Boman; [2022]
    Keywords : Paperboard; micromechanics; multiscale; fiber; X-ray; RVE; Technology and Engineering;

    Abstract : This thesis considers an investigation into the possibilities of creating a reasonably accurate multiscale material model for paperboard, with geometry based on X-ray scans of small paperboard samples. The modeling takes place in the software Multiscale Designer by Altair Engineering Inc. READ MORE

  4. 3. Micromechanical modelling of creep in wooden materials

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Oskar Falkeström; Kevin Coleman; Malin Nilsson; [2021]
    Keywords : Creep; RVE; Homogenization; Honeycomb; Tracheid; Comsol Multiphysics; Micromechanical modelling; Orthotropic; Parametric study; S2 material; Norwegian Spruce; Scots Pine; Cell geometry;

    Abstract : Wood is a complex organic orthotropic viscoelastic material with acellular structure. When stressed, wood will deform over timethrough a process called creep. Creep affects all wooden structureand can be difficult, time-consuming and expensive to measure. For this thesis, a simple computer model of the woodenmicrostructure was developed. READ MORE

  5. 4. Micro-architectured materials for noise and vibration control in high voltage products – design and modelling

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Alec Chamberlain; [2021]
    Keywords : Microarchitectured; lattice; elasticity; viscoelasticity; computational; homogenization;

    Abstract : Many Hitachi ABB Power Grids (HAPG) products vibrate and emit noise, but legal limitations of these parameters fuel the development of energy absorption methods used on products. Methods such as Constrained Layer Damping (CLD). READ MORE

  6. 5. Methods for modelling lattice structures

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Mona Kouach; [2019]
    Keywords : Lattice structures; Finite element method; Homogenization; Representative volume element;

    Abstract : The application of lattice structures have become increasingly popular as additive manufacturing (AM) opens up the possibility to manufacture complex configurations. However, modelling such structures can be computationally expensive. READ MORE
