Abstract:This paper presents a so-called epsilon-relaxed approach for structural topology optimization problems of discrete structures. The distinctive feature of this new approach is that unlike the typical treatment of topology optimization problems based an the ground structure approach, pre eliminate the singular optima from the problem formulation and thus unify the sizing and topology optimization within the same framework, hs a result, numerical methods developed for sizing optimization problems can be applied directly to the solution of topology optimization problems without any further treatment. The application of the proposed approach and its effectiveness are illustrated with several numerical examples.
