  1. 1. Tomography-based Micromechanical Analysis of Novel Composite Material

    University essay from KTH/Hållfasthetslära

    Author : Mattias Grankvist; [2023]
    Keywords : paper mechanics; micro mechanics; numerical analysis; tomography; foam forming; density profile; pappersmekanik; mikromekanik; numerisk analys; tomografi; skumformning; densitetsprofil;

    Abstract : This study explores the performance of porous Paptic paper materials composed of a mixture of softwood and lyocell fibers. The investigation involves laboratory experiments and numerical simulations to analyse the impact of various parameters on the paper's characteristics. READ MORE

  3. 2. 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. Micromechanical study of PFZ in aluminum alloys

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Hossein Shariati; [2016]
    Keywords : precipitate-free zones; strain gradient plasticity; mikromekanik;

    Abstract : There are a number of experiments showing that the ductility of aluminum alloys decreases during age-hardening heat treatment. Observing the grains of age-hardened aluminum alloys at the micron scale, one can notice that there are precipitate-free zones (PFZs) along the grain boundaries. READ MORE

  6. 5. Micromechanical Numeric Investigation of Fiber Bonds in 3D Network Structures.

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : YAĞIZ AZİZOĞLU; [2014]
    Keywords : Finite element; strength additive; 3D model; fiber network model; contact stiffness; paper strength; AFM; fiber adhesion.;

    Abstract : In manufacturing of paper and paperboard, optimized fiber usage has crucial importance for process efficiency and profitability. Dry strength of paper is one of the important quality criteria, which can be improved by adding dry strength additive that affect fiber to fiber bonding. READ MORE
