Design and Additive Manufacturing of 3D Phononic Band Gap Structures Based on Gradient Based Optimization

We present a novel approach for gradient based maximization of phononic band gaps. The approach is a geometry projection method combining parametric shape optimization with density based topology optimization. By this approach, we obtain, in a two dimension setting, cellular structures exhibiting re...
