Abstract

We use shape optimization and topology search to design families of microstructures approximating the ideal shock-protecting behavior. We present an algorithmic pipeline for the optimal design of such families combining differentiable nonlinear homogenization with self-contact and an optimization algorithm. We fabricate the designs with existing 3D printing technologies and validate their effectiveness through experimental testing.

Keywords
