  1. 16. Finite Element Modeling of Short, Randomized Fiber Composite Material

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Simone Ambrogio; [2020]
    Nyckelord :;

    Sammanfattning : With the advent of hybrids and electric vehicles, the need for lightweight and highperformancematerials is growing. Sheet molding compound (SMC) is a compositemade of short and randomized  bers that o ers a substantial weight reduction andgood mechanical properties while meeting the demand for large volume production.

  3. 17. Prediction of paperboard thickness and bending stiffness based on process data

    Master-uppsats, KTH/Hållfasthetslära (Avd.)

    Författare :Sacha Vandenbossche; [2019]
    Nyckelord :;

    Sammanfattning : Bending stiness is one of the most important mechanical properties in paperboard making,giving rigidity to panels and boxes. This property is currently only possible to measure bydestructive measure o the production line. LÄS MER

  4. 18. Simmulating pullout forces in particleboard

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Tapiwanashe Phiri; Niklas Björkman; [2019]
    Nyckelord :transversely isotropic material; orthotropic material; particleboard; finite element analysis; material model;

    Sammanfattning : Pull-out forces of screws and connectors in particleboard are particularly important when designing for strength and, or assembly in the furniture industry. The aim of this thesis was to develop a simulation model of particleboard that can predict pull-out forces of screws better than the currently used simulation model at IKEA of Sweden. LÄS MER

  5. 19. Modelling cross-laminated timber floors in dynamic analysis - Eigenfrequency prediction

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Författare :Johannes Wetterholt; [2019]
    Nyckelord :finite element method; FEM; dynamic analysis; Eigenfrequency; CLT; cross-laminated timber; cross-laminated timber floors; wooden floors; Technology and Engineering;

    Sammanfattning : In the late 1990s cross-laminated timber (CLT) was developed. The development of CLT was a project aimed to produce a structural product that could compete with the concrete industry and contribute to a reduced effect on the environment, due to the low environmental impact of timber in relation to other building materials.

  7. 20. Finite element analysis of e-commerce cushioning in corrugated board

    Master-uppsats, KTH/Hållfasthetslära (Avd.)

    Författare :Dominykas Gudavicius; [2018]
    Nyckelord :;

    Sammanfattning : Corrugated board and other paper products are widely used in product packaging due to good mechanical properties, recyclability, price etc. Due to the growing e–commerce industry the dynamical behaviour of corrugated board is of particular interest. Paper exhibits an orthotropic behaviour and is a non–linear material. LÄS MER
