摘要: Materials with a negative Poisson's ratio (auxetic materials) demonstrate the fascinating property of becoming fatter when stretched. This phenomenon is fundamentally important to properties material and significant change in value has effects on material's mechanical performance. article describes foams that show better indentation resilience than conventional positive ratio. The unusual auxetic are attributed deformation characteristics re-entrant (concave polyhedral) cell structures.
