论文摘要
具有可动元素的材料，歇斯底里，表现出记忆效果。通常，这些冲突很难直接观察或控制。在这里，我们介绍了一种机械超材料，其中细长的元素与推动者相互作用，充当机械的伴奏。我们展示了如何通过这些元素的几何设计来调整循环压缩下的海德氏菌性质和途径，以及如何通过倾斜一个边界来调整给定样品的途径。此外，我们研究了全局剪切模式与歇斯底州的耦合的效果，以此为例，以hyder子和非妓女自由度之间的相互作用为例。我们希望我们的工作能够激发有关设计师物质的进一步研究，并具有针对性的途径。
Materials which feature bistable elements, hysterons, exhibit memory effects. Often these hysterons are difficult to observe or control directly. Here we introduce a mechanical metamaterial in which slender elements, interacting with pushers, act as mechanical hysterons. We show how we can tune the hysteron properties and pathways under cyclic compression by the geometric design of these elements and how we can tune the pathways of a given sample by tilting one of the boundaries. Furthermore, we investigate the effect of the coupling of a global shear mode to the hysterons, as an example of the interactions between hysteron and non-hysteron degrees of freedom. We hope our work will inspire further studies on designer matter with targeted pathways.
