Abstract

Microstructures can lead to homogeneous materials with negative Poisson’s ratio, the so-called auxetics. An automatic way to create such microstructures is provided by topology optimization for compliant mechanisms. Nonconvexity is addressed by a suitable hybrid algorithm, based on differential evolution. This technique is demonstrated in the present paper with numerical examples.
