摘要: Abstract In this paper we propose different classes of isotropic microstructured media with tunable Poisson's ratio. The elastic periodic systems are continuous porous and two- three-dimensional lattices. microstructural parameters can be tuned in order to have an effective ratio equal zero. connection between properties is shown detail both analytically numerically.
