摘要: Auxetic structures exhibiting negative Poisson's ratios are disclosed including planar auxetic formed from x-axis and y-axis strands of selected waveforms. Portions the structure referred to as unit cells comprise four joints by two adjacent overlapping display symmetry about x y axes. Each cell comprises sub-unit segments ½ wavelength wave form. The may be into three-dimensional or cylindrical spherical structures.
