Fig. 5: Programming periodic localizations in 2D metamaterials based on the general framework.
From: Programmable and robust static topological solitons in mechanical metamaterials
a, b Illustrations of the evolution of the effective on-site potential with compressive strain, and the structural phase transition mechanism of the multistable systems. This general framework identifies the mechanism and provides the guideline for exciting static periodic solitons in metamaterials. c, d Unit cells and periodic localizations underlying the static kink/antikink excitations in Block-Spring and Rod-Spring metamaterials, respectively. The deformed configurations are shown at a compressive strain \(\varepsilon =9.5 \% \). The architectures of the unit cells, and comparisons among the experimental, numerical and theoretical results of these metamaterials are shown in detail in the Supplementary Figs. 10–12.
