Beaded metamaterials.

Abstract

Beading transforms flexible fiber networks into load-bearing structures by incorporating rigid, discrete elements in programmable weave patterns. Beaded assemblies function as mechanical metamaterials, where emergent mechanical behaviors arise from the interplay between geometry and material properties. Here, we investigate how this interplay governs the global mechanics of bead-thread networks. Using a combination of experiment and simple modeling, we identify conditions under which beaded structures undergo superjamming - a mechanically locked state that dramatically enhances load capacity. Our results show how potentially limiting factors such as gravity and friction can be leveraged to extend the domain of soft materials design into applications that demand rigidity.
