The article “Kresling tubemetamaterial exhibits extreme large-displacement buckling behavior” is now published in the journal Mechanics Research Communications.

The article, written by Emilio Turco, Emilio Barchiesi, Francesco dell'Isola, Andrea Causin and Margherita Solci, proves that Kresling-patterned origami tube metamaterials can exhibit nonlinear buckling behavior in compression characterized by extremely significant and sudden torsion as well as extreme transverse expansion/contraction.

It has been shown that this extreme buckling behavior can be achieved by adjusting the ratio of stiffness parameters that control the relative compliance of in-plane deformation of the facets with respect to their bending and folding on the folds. The modeling strategy adopted in this paper is discrete in nature and consists of an extensional-rotational spring model in which energy barriers are introduced to prevent the interpenetration of adjacent facets.
