Metamaterials usually refer to artificial composite materials consisting of an array of periodically arranged microstructures, engineered to provide unusual material properties that may not be easily found in nature. This paper proposes a new topological shape optimization method for systematic computational design of a type of mechanical metamaterials with negative Poissons ratios (auxetic materials), which integrates the numerical homogenization approach into a powerful parametric level set method (PLSM).
