  1. 1. 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.

  3. 2. Mechanical performance of NCF composites

    Författare :David Mattsson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Composite materials are today in widespread use in the aerospace and marine industries due to their excellent strength and stiffness to weight ratio. In most marine and aerospace applications traditional composites (pre- impregnated tapes) are still the main choice for design of load bearing structures. LÄS MER

  4. 3. Flexural Buckling of High-Strength Steel Columns

    Författare :Gabriel Sabau; Ove Lagerqvist; Torsten Höglund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stålbyggnad; Steel Structures;

    Sammanfattning : The European standards dealing with design rules and recommendations for steel structures have been under revision in the past years due to the increased use of high-strength steels. High-strength steels popularity increased at a steady pace in the last decades since they allow for more light-weighted solutions than conventional steels. LÄS MER
