The present contribution proves that Kresling-patterned tubular origami metamaterials can exhibit a nonlinear buckling behavior in compression characterized by extremely significant and sudden twisting, as well as by extreme transverse dilation/contraction. It is proved that such an extreme buckling behavior can be achieved by tuning the ratio between stiffness parameters controlling the relative compliance of in-plane deformation of facets with respect to their bending and folding about creases. The modeling strategy adopted in the present contribution is discrete in nature and consists of an extensional-rotational spring model where energy barriers are introduced to prevent the interpenetration of adjacent facets.

目前的贡献证明，Kresling 图案的管状折纸超材料可以在压缩时表现出非线性屈曲行为，其特征是极其显着和突然的扭曲，以及极端的横向膨胀/收缩。事实证明，这种极端的屈曲行为可以通过调整刚度参数之间的比率来实现，该刚度参数控制面内变形相对于折痕周围的弯曲和折叠的相对顺应性。本贡献中采用的建模策略本质上是离散的，由拉伸旋转弹簧模型组成，其中引入能量势垒以防止相邻面的相互渗透。
