在双稳态褶皱中切孔
Cutting holes in bistable folds
摘要：
折叠的盘是双稳态的，因为它可以通过折叠上的小的高度变形区域中局部化的弹性能量而弹出到反转状态。切掉这个奇异性会使周围的材料松弛，当孔的尺寸达到临界尺寸时，会导致双稳态的损失。这些尺寸是强各向异性的，并且具有令人惊讶的凹入行为，使得去除额外的材料可以重新稳定反转状态。一个模型的表面作为一个广泛的环形可展带被发现捕捉定性的观察实验和模拟。这些现象是必然的力学和设计的褶皱弹性片，可展开的表面，折纸和kirigami，和其他部署和顺应性的结构。
英文摘要：
A folded disk is bistable, as it can be popped through to an inverted state with elastic energy localized in a small, highly-deformed region on the fold. Cutting out this singularity relaxes the surrounding material and leads to a loss of bistability when the hole dimensions reach a critical size. These dimensions are strongly anisotropic and feature a surprising re-entrant behavior, such that removal of additional material can re-stabilize the inverted state. A model of the surface as a wide annular developable strip is found to capture the qualitative observations in experiments and simulations. These phenomena are consequential to the mechanics and design of crumpled elastic sheets, developable surfaces, origami and kirigami, and other deployable and compliant structures.
