  2. 11. Modelling Damage Evolution and Fracture of Paper Materials

    Author : Rickard Hägglund; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paper material; Fracture mechanics; Tensile strength; Fibre network; Continuum damage mechanics; Non-local theory;

    Abstract : This thesis contains six papers dealing with different aspects of damage and fracture in paper. The work addresses the problem of material length scales in the context of deformation and fracture of paper materials. READ MORE

  4. 12. On steady waves in two-layer fluids and ferrofluids

    Author : Dag Nilsson; Partiella differentialekvationer; []
    Keywords : Internal waves; ferrofluids; partial differential equation; nonlinear waves; travelling waves; solitary waves; dynamical systems; Hamiltonian systems; non-local equations;

    Abstract : This thesis concerns travelling waves in a two-layer fluid and on a ferrofluid jet. We prove existence of several types of such waves by reformulating the corresponding governing equation as an infinite dimensional dynamical system, where an unbounded spatial coordinate is used as time.

  5. 13. Theory of van der Waals bonding: from bulk materials to biomolecules

    Author : Elisa Londero; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; alkanes; extended systems; DNA; band structure; van der Waals Density Functional vdW-DF ; exchange functionals; Density Functional Theory; non-local correlation; layered oxides;

    Abstract : Sparse matter is abundant in Nature.It encompasses systems characterized by an intrinsic low density of electrons in sizeable regions, where the van der Waals forces contribute considerably to cohesion.Given the length scale of the problem, a prediction of these materials requires appropriate tools within a quantum-mechanical framework.

  6. 14. On the Relations between Driving Patterns, Exhaust Emissions and Network Characteristics in Urban Driving

    Author : Lena Smidfelt-Rosqvist; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic calming; intersections; driving adaptation; speed limits; Road transport technology; driving behaviour; Vägtransportteknik; overall effects; trip-long; non-local effects;

    Abstract : The planning and design of street networks in cities influence driving behaviour and give rise to variations in driving patterns (i.e., speed and acceleration profiles) that affect exhaust emissions and fuel consumption. READ MORE
