  1. 1. Cam Roller Contact

    Författare :Frederic Cabanettes; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; classification of surfaces; wear test; roller; rough contact model; surface topography; injection cam; manufacturing evaluation;

    Sammanfattning : The automotive industry and the design of engines are strongly ruled by performance andlegislation demands. First order aspects defining the main functions of a component are wellknown and new challenges appear at a lower scale. LÄS MER

  3. 3. Beam-to-Beam Contact and Its Application to Micromechanical Simulation of Fiber Networks

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Hamid Reza Motamedian; Artem Kulachenko; Umberto Perego; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber network; beam-to-beam contact; rotational contact; non-consistent; simulation; finite element; multiscale; microscale; micromechanics; paper; refining; beating; fine; hygroexpansion; shrinkage; drying; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : This doctoral thesis covers the topic of modeling the three-dimensional fiber net- works with the finite element method. It contains the part addressing the numerical aspects of the modeling, namely, the contact formulation and application of the developed methods to the fundamental questions such as the effect of randomness in fiber properties and effect of fines and hygroexpansion.

  4. 4. Non-contact surface wave measurements on pavements

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Henrik Bjurström; Nils Rydén; Björn Birgisson; Jinying Zhu; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; seismic testing; asphalt concrete; dynamic modulus; non-contact measurements; rolling measurements; surface waves; Lamb waves; MEMS microphones; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : In this thesis, nondestructive surface wave measurements are presented for characterization of dynamic modulus and layer thickness on different pavements and cement concrete slabs. Air-coupled microphones enable rapid data acquisition without physical contact with the pavement surface. LÄS MER

  5. 5. The Significance of Spaciousness: an investigation of spaciousness in the context of the residential yard

    Detta är en avhandling från Lund Institute of Technology

    Författare :Eva Kristensson; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interior design; density; Spaciousness; densification; courtyard; residential yard; open space; Architecture; housing environment; Arkitektur; inredningsarkitektur;

    Sammanfattning : The new interest in density displayed by professional town planners and town-planning researchers is related to the present densification of the urban environment in many towns and cities. Research on densification is primarily concerned with the link between urban form and sustainable development. LÄS MER
