论文摘要
正性超材料由定期在太空中的元素组成。该元素包括两个长方体结构。第一个结构是元素的基本结构,第二个结构是元素的第一个结构的转换。该元件的第一个结构是由由8个节点连接的24个bar组成的立方结构,该元件的第二个结构是由14个节点连接的36个bar组成的立方结构。该超材料具有6个独立的弹性常数,因此材料设计具有很大的自由度。使用简单的通用设计方法,可以设计具有量身定制弹性常数的超材料。因此,它在机械超材料,弹性波 - 材料,声学超材料和地震超材料的领域具有巨大的应用价值,并为实现控制弹性波,声波和振动的梦想奠定了基础。
An orthotropic metamaterial is composed of elements arrayed periodically in space. The element includes two cuboid structures. The first structure is the basic structure of the element, and the second structure is the transformation of the first structure of the element. The first structure of the element is a cuboid structure composed of 24 bars connected by 8 nodes, and the second structure of the element is a cuboid structure composed of 36 bars connected by 14 nodes. This metamaterial has 6 independent elastic constants, so there is a large degree of freedom in material design. Using a simple universal design method, a metamaterial with tailored elastic constants can be designed. Therefore, it has great application value in the fields of mechanical metamaterials, elastic wave metamaterials, acoustic metamaterials, and seismic metamaterials, and has also laid the foundation for realizing the dream of controlling elastic waves, acoustic waves and vibrations.
