  1. 1. 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.

  2. 2. 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.
