  2. 1. On Cohesive Modelling of Carbon/Epoxy Composites : Delamination and Fibre Compressive Failure

    Author : Daniel Svensson; Ulf Stigh; Bent Sørensen; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFRP; Cohesive zone model; J-integral; LEFM; Delamination; Compressive failure; Technology; Teknik; Mechanics of Materials; Materialmekanik;

    Abstract : 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.

  4. 2. Modelling of intergranular stress corrosion cracking mechanism : Du som saknar dator/datorvana kan kontakta [email protected] för information

    Author : Michal Sedlak Mosesson; Bo Alfredsson; Thierry Couvant; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cohesive Zone Model; Fracture Mechanics; Diffusion; Duplex oxide; Multi-physics; Finite Element Model; Engineering Mechanics; Teknisk mekanik;

    Abstract : When assessing nuclear power plant life, stress corrosion cracking (SCC) plays an important role. Stress corrosion cracking in nuclear power plants is well recognized and heavily researched. Still due to its complicated nature it is not completely understood. There are many different damage mechanisms behind SCC. READ MORE

  5. 3. Modelling and Reliability Assessment of Microsystem Interconnections

    Author : Yan Zhang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cohesive zone model; discontinuous regularization; Micropolar theory; homogenization; microsystem interconnection;

    Abstract : With the continuous increase of packaging density, the electronic component size and, in particular, the thickness of the involved interconnections decrease significantly. In addition, the microsystem interconnects usually include even finer internal structures. READ MORE

  6. 4. Adhesive joining for crashworthiness : material data and explicit FE-methods
