  1. 1. Investigation of the Applicability of Fracture Mechanics for Tissue Paper

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Albin Boestad; [2023]
    Nyckelord :Tissue Papper; Fracture Mechancis; Embossing; Mjukpapper; Brottmekanik; Prägling;

    Sammanfattning : Tissue paper is a common type of paper material and is used in a variety of products. For tissue paper, several properties are of interest, such as absorbency, softness, bulk and mechanical properties. Embossing is an operation used to apply a pattern on tissue paper. LÄS MER

  3. 2. Fatigue Crack Growth Analysis in Python algorithm with Finite Element Methods : Numerical Simulation of Fatigue Crack Growth

    Master-uppsats, Karlstads universitet

    Författare :Hasan Majid; [2022]
    Nyckelord :;

    Sammanfattning : The goal of this thesis was to construct and develop a python-based finite element computer program for the evaluation of fatigue crack growth rate in notched metallic rods. The simulation was done by implementing elastic stress theory and linear elastic fracture mechanics techniques. LÄS MER

  4. 3. Design of passively loaded specimen for constant KI during crack growth

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Liisa Tofferi; [2021]
    Nyckelord :constant KI; passively loaded specimen; konstant KI; passivt belastad provstav;

    Sammanfattning : Passive loading of a specimen is a relatively cheap method to use in fracture mechanical testing compared to an actively loaded specimen. For stress corrosion cracking testing it is easier to use a passively loaded specimen since the specimen easily can be placed in a specific corrosive environment. LÄS MER

  5. 4. Evaluation of cracks in corrugated board, Evaluating cracks using Finite Element Method and J-integral

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Ming-Yang Li; [2021]
    Nyckelord :corrugated board; corrugated box; finite element method; fracture mechanics; mechanical properties; wellpapp; finita elementmetoden; frakturmekanik; mekaniska egenskaper;

    Sammanfattning : This report investigates whether a FEM model can be used to assess the risk of crack growth in corrugated board. A set of box geometries with cracks at different locations were loaded and then compared using the evaluated J-integral within the FEM software. LÄS MER

  7. 5. Evaluation of Peridynamics and Its Application in Harmonic-Structured Material Simulations

    Master-uppsats, Lunds universitet/Mekanik

    Författare :Theodor de Sousa; [2020]
    Nyckelord :peridynamics; peridigm; harmonic-structured materials; computational mechanics; fracture modelling; Technology and Engineering;

    Sammanfattning : Materials are constantly sought to be improved in different manners. Two of the most common characteristics to improve are strength, and ductility. Historically, materials are modified homogeneously to achieve improvement, while the past century has also seen composite materials becoming standard-issue within various industries. LÄS MER
