  1. 1. Mixed mode loaded adhesive layers : from measurement of material data to analysis of structural behaviour

    Detta är en avhandling från Chalmers tekniska högskola

    Författare :Jia Li Högberg; Högskolan i Skövde.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik; Teknik; Technology; adhesive layer; mixed mode testing; cohesive law; J-integral;

    Sammanfattning : In manufacturing of multi-material products, a joining method that is able to cost-effectively assemble components made of dissimilar and similar material, with irregular geometries, is optimal. As an alternative, adhesive bonding is in-creasingly adapted by the industry, which is also used in manufacturing of multi-phase materials. LÄS MER

  2. 2. Shear Behaviour of Adhesive Layers

    Detta är en avhandling från Chalmers tekniska högskola

    Författare :Karin Leffler; Högskolan i Skövde.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik; Teknik; Technology; Adhersive layer; shear; ENF-specimen; stress-deformation relation; experimental method; J-integral; inverse method;

    Sammanfattning : An experimental method to determine the complete stress versus deformation relation for a thin adhesive layer loaded in shear is presented. The work is based on a classical specimen geometry, i.e. the end-notch flexure specimen (ENF-specimen) and the experiments are evaluated based on an inverse method. LÄS MER

  3. 3. Application of cohesive modeling in joining technology : Thick adhesive layers and rivet joints

    Detta är en avhandling från Chalmers University of Technology

    Författare :Saeed Salimi; Högskolan i Skövde.; Högskolan i Skövde.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technology; rivet joints; mixed-mode cohesive failure; mixed material; J-integral; Thick adhesive layer;

    Sammanfattning : This thesis summarizes the development of cohesive modeling of joints. It presents some new developments regarding the effects of non-zero thickness of adhesive layers and a novel approach of using the concept of cohesive modeling to characterize the failure behavior of rivet joints.

  4. 4. On Cohesive Modelling ofCarbon/Epoxy Composites Delamination and Fibre Compressive Failure

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Daniel Svensson; Högskolan i Skövde.; Högskolan i Skövde.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology; Teknik; Mechanics of Materials; Materialmekanik; CFRP; Cohesive zone model; J-integral; LEFM; Delamination; Compressive failure;

    Sammanfattning : Carbon Fibre Reinforced Polymers are widely used in engineering applications where weight saving and high mechanical performance are a key factors. However, an inheren tweakness of laminated CFRP:s is there relatively low resistance to delamination. Therst part of this thesis is devoted to extract cohesive laws associated with delamination.
