摘要：
The paper introduces a new alternative towards fabrication of auxetic metamaterials (materials with negative Poisson's ratio) controlled by geometric transformations. These transfoimations are derived from the theory of small (infinitesimal) elastic deformation superimposed on finite elastic deformations. By using this theory, a cylindrical region filled with initial deformed foam is transformed through deformation into a cylindrical shell region filled with auxetic metamaterial. As an example, the realization of the seismic cloak device becomes a practical possibility.
