我们讨论的方法,可逆地诱导不可开发的表面从可扩展的片材的材料在微观尺度上的宏观物体。我们分析了在膜近似下,对于拓扑荷+1的向错缺陷,玻璃的弹性基态作为温度的函数。一个目的是表明,通过将适当的指向矢场写入这样的固体,可以创建一个具有高斯曲率的表面,可以动态地从可伸缩片切换,同时避免拉伸能量。除了可编程结构的前景之外,这样的表面通过薄系统中的拉伸提供致动,因为当随后移除照明时,不可避免的拉伸返回。
We discuss methods of reversibly inducing non-developable surfaces from flat sheets of material at the micro-scale all the way to macroscopic objects. We analyse the elastic ground states of a nematic glass in the membrane approximation as a function of temperature for disclination defects of topological charge + 1. An aim is to show that by writing an appropriate director field into such a solid, one could create a surface with Gaussian curvature, dynamically switchable from flat sheets while avoiding stretch energy. In addition to the prospect of programmable structures, such surfaces offer actuation via stretch in thin systems since when illumination is subsequently removed, unavoidable stretches return.
