Topology optimization with design-dependant using simultaneous shape and topology variation
(English)Manuscript (preprint) (Other academic)
We present a new method for topology optimization with design-dependent loads. In traditional topology optimization a fixed design domain on which the loads and constraints are specified is used. Such an approach can not handle loads which depend on the design. Here we introduce domain shape variation. using techniques from shape optimization, simultaneously with topology optimization. For topology optimization we use the SIMP interpolation function together with a filter as restriction method. The stiffness of the structure is maximized given a limited alllount of material. Three numerical examples are presented which illustrates the proposed method.
