    About the course

    Aim

    In structural optimization we study the problem of finding the best mechanical design. The word "best" has to be given a certain meaning, it could be to minimize the structural weight or to maximize the stiffness. The course aims at giving knowledge and understanding of how such maximum efficient load-carrying structures may be obtained, and skill in using the corresponding computer based tools. After the course the students should be able to

    • Formulate engineering design problems for load carrying structures as optimization problems, using both size, shape and topological variables.
    • Solve small-scale discrete problems.
    • Describe numerical algorithms suitable for structural optimization problems.
    • Solve some continuous structural optimization problems using calculus of variations.
    • Use and describe the general steps involved in solving large scale shape and topology optimization problems.

    Content

    Basic concepts. Classification of structural optimization problems. Lagrangian duality. Calculus of variations and energy principles in solid mechanics. Explicit approximations: SLP, SQP, CONLIN, OC, MMA. Sensitivity analysis. Shape optimization. Structures of maximum stiffness and topology optimization. The SIMP-method. Computer exercises.
