Abstract

Abstract : Perforated systems with quasi‐disordered arrays of slits are found to exhibit auxetic characteristics almost as much as their traditional ordered "rotating‐squares" counterparts. This provides a highly robust methodology for constructing auxetics that may be used for various practical applications such as skin grafting, where a high degree of precision may not always be achievable.
