Abstract
Micro-structured materials with a negative Poisson ratio are termed auxetic. In a Research News (p. 2669), Mitschke et al. demonstrate how the geometric analysis of periodic tessellations or tilings can help identify novel auxetic material designs. At least some of the tessellations that are auxetic in a “skeletal structure” model are also auxetic when realized as a linear-elastic cellular structure, produced for example by selective electron beam melting.
