A sequential coupling of shape and topology optimization for structural design

We consider different algorithms to design lightweight and stiff structures exhibiting free-form features. First we apply a shape optimization and a topology optimization procedure, separately. Then, we couple these two techniques sequentially. Topology optimization is also enhanced by a structure-tailored computational mesh, made it possible by anisotropic mesh adaptation. This allows us to obtain an intrinsically smooth final layout which can be directly moved on to the production manufacturing phase. An extensive numerical assessment corroborates both qualitatively and quantitatively the performances of the proposed algorithms.
