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

    University dissertation from Chalmers tekniska högskola

    Author : Svante Alfredsson; Högskolan i Skövde.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP; Teknik; Technology; adhesive layer; constitutive behaviour; fracture; energy release rate; shear fracture; mode-mixity; experimental method; inverse solution; multi-material joints;

    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

  2. 2. Cemented Carbide Sintering Constitutive Relations and Microstructural Evolution

    University dissertation from Stockholm : Materialvetenskap

    Author : Anders Petersson; KTH.; [2004]
    Keywords : Cemented carbides; Sintering; Constitutive relations; Microstructure; Densification; Modelling;

    Abstract : Cemented carbides based on tungsten carbide and cobalt arecommonly produced by a powder metallurgy route including liquidphase sintering. The pressed compact densifies to almost halfits volume during sintering due to pore elimination. READ MORE

  3. 3. Modelling and simulation of plastic deformation on small scales interface conditions and size effects of thin films

    University dissertation from Stockholm : KTH

    Author : Per Fredriksson; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strain gradient plasticity; Size effects; Thin films; Interface; Finite element method; Dislocations; Constitutive behaviour; Hardening behaviour; Indentation; Contact mechanics; Metal matrix composites; TECHNOLOGY Engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik;

    Abstract : Contrary to elastic deformation, plastic deformation of crystalline materials, such as metals, is size-dependent. Most commonly, this phenomenon is present but unnoticed, such as the effect of microstructural length scales. READ MORE

  4. 4. Behaviour and modelling of a natural soft clay triaxial testing, constitutive relations and finite element modelling

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Bo Westerberg; Luleå tekniska universitet.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : The main objectives if the research project have been to create an experimental basis for a more general theoretical modelling of Swedish clays and to improve the knowledge of the mechanical behaviour of natural soft clays. Another objective has been to investigate the effects of end restraint on the mechanical behaviour obtained in triaxial tests, by means of numerical simulations. READ MORE

  5. 5. Plastic behaviour of steel experimental investigation and modelling

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jonas Gozzi; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : This thesis deals with the plastic behaviour of steel. It comprises an investigation with focus on biaxial tests and constitutive modelling. Tests were performed on one stainless steel grade in two different strength classes, C700 and C850, as well as one extra high strength structural steel grade. READ MORE
