  1. 1. Shear Behaviour of Adhesive Layers

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

    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

  2. 2. Experimental methods to determine model parameters for failure modes of CFRP

    Författare :Daniel Svensson; Ulf Stigh; Svante Alfredsson; Högskolan i Skövde; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; composite; delamination; compressive failure; energy release rate; cohesive modelling; Teknik; Technology;

    Sammanfattning : The focus of this thesis is to develop methods to predict the damage response of Carbon Fibre Reinforced Polymers (CFRP). In the pursuit of reducing the manufacturing cost and weight of CFRP components, it is crucial to enable modelling of the non-linear response associated with various failure modes. LÄS MER

  3. 3. Constitutive Behaviour and Fracture of Adhesive Layers : Inverse Methods and Energetic Balance

    Författare :Svante Alfredsson; Högskolan i Skövde; []
    Nyckelord :adhesive layer; constitutive behaviour; fracture; energy release rate; shear fracture; mode-mixity; experimental method; inverse solution; multi-material joints; TECHNOLOGY; TEKNIKVETENSKAP; Teknik; Technology;

    Sammanfattning : In the automobile industry, current demands on reduced emissions with maintained or even increased crash worthiness, forces the industry to seek weight-reducing designs. The possibility to use lightweight materials is obviously attractive. At joints, these lightweight materials have to be connected to high-strength or low-cost materials. LÄS MER
