Parameter free structural optimization applied to the shape optimization of smart structures

•We apply structural optimization to smart structures, using sensitivity filtering.•Vertex morphing is applied for generating complex beads, allowing high flexibility.•The effect of gradient filtering onto complex shape optimization tasks is discussed.•Shape optimization and sizing are applied to a real-application smart structure.

This contribution applies structural shape optimization techniques to actuated smart structures. In order to combine these two disciplines, the idea of Optimal Actuation and an enlarged filtering scheme are presented. A parameter free optimization scheme is used, which allows the treatment of different branches of structural optimization using an identical framework.
