  4. 7. Tensile fracture of ice : test methods and fracture mechanics analysis

    Author : Lars Stehn; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : This thesis is concerned with several aspects of fracture of both brackish (low salinity) sea ice and freshwater ice. The tests and analyses are confined to tensile, or in fracture mechanics language, Mode I, fracture. READ MORE

  5. 8. 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

  6. 9. Frictional Effects on Hertzian Contact and Fracture

    Author : Denis Jelagin; Per-Lennart Larsson; Bertil Storåkers; David Hills; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contact mechanics; Elastic material; Friction; Nanoindentation; Fracture; Solid mechanics; Fastkroppsmekanik;

    Abstract : This thesis addresses normal axisymmetric contact of dissimilar elastic solids at finite interfacial friction. It is shown that in the case of smooth and convex but otherwise arbitrary contact profiles and monotonically increasing loading a single stick-slip contour evolves being independent of loading and profile geometry.

  7. 10. On fracture of layered materials

    Author : Jens Gunnars; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : This thesis is concerned with fracture in layered bimaterials. Fracture of coatings is considered to some extent. The behaviour of cracks growing normal to bimaterial interfaces is studied with the objective to clarify conditions for crack-tip shielding and amplification. READ MORE
