Characterization of a reversible-assembly mechanical metamaterial with an adjustble mechanical property by WU Qi, YANG Yu, LU Yifei, BAO Panpan, WANG Zhigang

“…The results show that the three basic voxels have great rigidity difference, and Poisson’s ratio covers the range from negative to positive.Therefore, different combination sequences of these three basic voxels can produce macro structures with different mechanical property distributions, which proves the rationality of using these three basic voxels as the basic voxels of the reversible-assembly structure.In addition, the mathematical relationship between geometric parameters and mechanical properties can provide guidance for the engineering application of such mechanical metamaterials.…”
