Simple Semi-auxetic Solids

摘要: Upon defining two types of semi-auxetic solids—directional and positional solids—this chapter develops the elastic properties a directional solid based on combined hexagonal re-entrant honeycomb structure 3D kinematic characteristics another rotating units. This is followed by an analysis proposed fabrication methods yarns. An then given for functionally-graded beam from positive Poisson’s ratio one surface to negative opposite surface. Finally analyses are mechanical structures in form compound rods sandwich . Results show that extent auxeticity depends not only constituent relative volume fractions, but also modes deformation, i.e. these exhibit overall conventional under type loading mode, auxetic different mode.
