    Sammanfattning : Friction stir welding (FSW) has undergone a rapid expansion in several industrial sectors such as in the aerospace, marine, railway and automotive sectors. Current industrial applications are mainly simple long straight welds, but there is a growth of interest in components with higher geometric complexity. LÄS MER

  3. 2. On Postbuckling Analysis of Thin-walled Structures Numerical and Statistical Approaches

    Författare :Mats Ander; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; postbuckling; hierarchical elements; imperfection sensitivity; displacement gradients; total Lagrange formulation; geometrically non-linear structures;

    Sammanfattning : Thin-walled structural elements, such as plates, shells and beams are important load carrying components in civil-, mechanical-, automotive- aeronautical- and marine engineering structures. In order to reduce the weight thin-walled structures are given an optimum design making them sensitive to unforeseen deviations in geometry, boundary conditions, material properties and applied loads.

  4. 3. Application of X-ray Computed Tomography for Assessment of Additively Manufactured Products

    Författare :Amir Reza Zekavat; Lars Pejryd; Leonardo De Chiffre; Örebro universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; X-ray computed tomography; Surface roughness;

    Sammanfattning : Additive Manufacturing (AM) is a novel method for fabricating parts from three-dimensional model data, usually by joining materials in layer upon layer fashion. The freedom of design in this method has resulted in new possibilities for fabrication of parts with complex geometries. LÄS MER

  5. 4. Tidal Inlets Hydraulics and Morphological Modeling: An application to Mundaú Lagoon, Brazi

    Författare :Almir Nunes De Brito Junior; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tidal inlets; Numerical modeling; Coastal lagoons; Mundaú Lagoon; Sururu; Sediment transport;

    Sammanfattning : Tidal inlets are narrow channels connecting coastal lagoons to the sea and in this way controlling the exchange of water while serving as navigational pathways. These important components of the coast are also very dynamic environments, having their morphology determined by multiple sediment transport processes, making tidal inlets difficult to model.
