Discretized Method for Topology Optimization

  • Conference paper
Discrete Structural Optimization

Abstract

After discussing the aims and significance of topology optimization, layout optimization of grid-like structures is discussed in detail. In the proposed method, the ground structure (structural universe) approach is used, together with continuum-type optimality criteria. Layout optimization may be carried out using (i) analytical methods for exact, often closed-form, continuum-type solutions or (ii) numerical methods for approximate, discretized solutions. Due to the high optimization capability of modern OC methods, the latter provides simultaneous optimization of geometry and topology, with a high degree of accuracy. Finally, a new, extended optimal layout theory for multiload, multipurpose structures is outlined and applications to particular classes of problems given.
