    Sammanfattning : This thesis explores using multi-scale topology optimization (TO) by utilizing inverse homogenization to automate the adjustment of each unit-cell's geometry and placement in a lattice structure within a pressure vessel (the design domain) to achieve desired structural properties. The aim is to find the optimal material distribution within the design domain as well as desired material properties at each discretized element and use machine learning (ML) to map microstructures with corresponding prescribed effective properties.

  7. 5. Viscoelasticity of transparent wood-polymer biocomposites : Measuring the time-dependence of a delignified birch and poly(methyl methacrylate) composite’s mechanical properties, using digital image correlation

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Marine Jeanne Debouvry; [2023]
    Nyckelord :;

    Sammanfattning : The viscoelastic behavior of a delignified birch and poly(methyl methacrylate) (PMMA) composite was investigated, in an effort to learn more about the mechanical properties of transparent wood-polymer biocomposites. Tensile creep tests with constant load were performed for native wood, non-delignified, and delignified wood-polymer composites. LÄS MER
