  1. 1. Virtual Material Testing of Adhesive Joints

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Vinit Jethalal Nagda; [2020]
    Nyckelord :;

    Sammanfattning : The automotive industry has shown an increasing interest in adhesive bonding for mixed-material joining. Modern design methods are critically dependent on accurate material models and data for numerical methods to enable the simulation of a design prototype early in the design process. LÄS MER

  3. 2. Characterization of thin laminate interface by using Double Cantilever Beam and End Notched Flexure tests

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Moiz Majeed; Rahitya Venkata Teja Geesala; [2020]
    Nyckelord :Double Cantilever Beam DCB ; End-Notched Flexure ENF ; Fracture toughness; Low density Polyethylene LDPE ; Three-point bending test;

    Sammanfattning : This thesis is intended to identify the mode I and mode II fracture toughness to characterize the thin laminate interface by using the Double Cantilever Beam test (DCB) and End Notched Flexure test (ENF). This study’s thin laminate was Polyethylene Terephthalate and Low-Density Polyethylene (PET-LDPE), which is mostly used by packaging industries in the manufacturing of packages to store liquid food.

  4. 3. Numerical analysis of paperboard delamination using cohesive elements

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Markus Johansson-Näslund; [2020]
    Nyckelord :;

    Sammanfattning : A new test method for measuring the shear strength associated with mode III delamination of paperboard is studied with the purpose of reducing the size of the test configuration. The method, which uses a split cantilever beam (SCB) specimen, measures the shear strength indirectly through the fracture resistance. LÄS MER

  5. 4. Investigation of the mechanical performance of metal-composite joints

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Marc Olavide Rubio; [2017]
    Nyckelord :carbon fiber epoxy; AlSi-coated boron steel; metal-composite joints; double-cantilever beam test; end-notched flexural test; tensile test;

    Sammanfattning : Composite materials are gaining the attention of several industries due to the high stiffness-to-weight and strength-to-weight ratios they offer. Especially in the automotive industry, demands on reduction of CO2 emissions is the major driving force towards lighter vehicles. LÄS MER

  7. 5. Comparison of ASTM and BSI Standards for the calculation of fracture energy of adhesives : Design of a fixture and testing of DCB specimens

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap; Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Francisco Manuel Rodríguez Moronta; Judith Segurola Lucas; [2015]
    Nyckelord :DCB; standards; adhesives; fracture energy;

    Sammanfattning : Modern synthetic structural adhesives are finding a place in the drive to improve the fuel efficiencyof automobiles through weight reduction of the structure. One of the most important properties ofthe adhesives used in this type of joining is the fracture energy. LÄS MER
