  1. 1. Simulations of experimental crack development in ceramic material with notched specimen

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Clas Dahlin; [2022]
    Nyckelord :Solid Mechanics; Fracture mechanics; Ceramics; Dynamics; Ballistics; Hållfasthetslära; Brottmekanik; Keramer; Dynamik; Ballistik;

    Sammanfattning : Low-density armour often uses ceramic materials, as their high compressive strength and relatively low weight make the material ideal for moving in the field. The ballistic protection works by redirecting the plastic flow of the projectile radially, which reduces penetration. LÄS MER

  3. 2. Monitoring of crack growth and crack mouth opening displacement in compact tension specimens at high temperatures : Development and implementation of the Direct Current Potential Drop (DCPD) method

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Philip Malmqvist; [2016]
    Nyckelord :DCPD; Crack Growth; Compact Tension Testing; CMOD;

    Sammanfattning : The mechanical engineering department at the University of Idaho is conducting a project with the purpose of developing a complete system for investigating creep-, creep-fatigue- and fatigue properties of metallic materials at elevated temperatures up to 650 ˚C with Compact Tension (CT) specimens. Considerable efforts have been made to study and understand these phenomena, although numerous problems still exist. LÄS MER

  4. 3. Fracture Analysis of the Working Part of an Impactor under Impact Loading

    Magister-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Han Shichang; Shen Yujie; [2011]
    Nyckelord :Dynamic analysis; 3PBS; Dynamic Stress Intensity Factor; CMOD;

    Sammanfattning : Based on a set of experiment picture collection, a 3-point bending specimen model under dynamic load is analyzed in two ways: one is derived by using vibration analysis method with consideration of equivalent system stiffness and damping. The other is using finite element method for ABAQUS software. LÄS MER
