  2. 1. Shear Behaviour of Adhesive Layers

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

    Abstract : 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. READ MORE

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

    Author : Svante Alfredsson; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; constitutive behaviour; fracture; energy release rate; shear fracture; mode-mixity; experimental method; inverse solution; multi-material joints; TECHNOLOGY; TEKNIKVETENSKAP; Teknik; Technology;

    Abstract : 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. READ MORE

  5. 3. Influences of temperature, fatigue and mixed mode loading on the cohesive properties of adhesive layers

    Author : Tomas Walander; Christian Berggreen; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; cohesive law; fatigue; finite element analysis; fracture energy; mixed mode; multi-axial fatigue; potential model; temperature; Mechanics of Materials; Materialmekanik;

    Abstract : This thesis concerns some aspects that have influence on the strength of adhesive layers. The strength is determined by the stress deformation-relation of the layer. This relation is also referred to as cohesive law. READ MORE

  6. 4. Mechanical behaviour of adhesive layers : experimental methods, cohesive laws, and fracture mechanics

    Author : Anders Biel; Kristofer Gamstedt; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experimental method; adhesive layer; cohesive law; fracture; fracture energy; energy release rate; peel; shear; Materials science; Teknisk materialvetenskap; Teknik; Technology;

    Abstract : Adhesive joining is today viewed as one of the key technologies to achieve decreased emissions in the automobile industry. To decrease weight, optimal material selection often results in different materials for different parts. This leads to the necessity to join mixed material. Here, the use of adhesives is the most promising joining technology. READ MORE
