DOI: 10.1016/j.jmps.2018.01.013
Abstract: Abstract This paper presents a systematic approach for designing 3D auxetic lattice materials, which exhibit constant negative Poisson’s ratios over large strain intervals. A unit cell model mimicking tensile tests is established and based on… read more here.
