    Sammanfattning : Concrete is one of the most commonly used construction materials, yet industrial fabrication continues to default to established standards of planar formwork and uniform cross-sections for the sake of simplicity and predictability. The research conducted within Concrete Form[ing]work explored alternative methods of producing concrete formwork with a simple, technical re-imagination of material: exchanging the familiar, i.

    Sammanfattning : Product development processes are continuously challenged by demands for increased efficiency. As engineering products become more and more complex, efficient tools and methods for integrated and automated design are needed throughout the development process. LÄS MER

  4. 3. Cut isogeometric methods on trimmed multipatch surfaces

    Författare :Tobias Jonsson; Mats G. Larson; Karl Larsson; Johan Hoffman; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cut finite element method; isogeometric analysis; Nitsche s method; a priori error estimation; parametric geometry; interface problem; surface CAD;

    Sammanfattning : Partial differential equations (PDE) on surfaces appear in a variety of applications, such as image processing, modeling of lubrication, fluid flows, diffusion, and transport of surfactants.  In some applications, surfaces are drawn and modeled by using CAD software, giving a very precise patchwise parametric description of the surface.

    Sammanfattning : The modern requirements on power transmissions focus on energy efficiency, low noise and dynamic vibrations, and power density. In order to meet these requirements, the gear wheels must be manufactured to very high precision. Additionally, it should be economical to manufacture these gears within the tight requested tolerances. LÄS MER
