Novel mechanical metamaterials inspired by single crystal boron arsenate built at the macroscale using conventional materials are presented and investigated through finite element simulations. It is shown that these mechanical metamaterials can mimic, to some extent, the properties of boron arsenate with the more robust rotating rigid-units mechanism being excellently replicated and even made to operate more efficiently through modifications of the geometry of the mechanical metamaterial. It is also shown that not all mechanisms causing auxeticity at the nanoscale can be upscaled due to the absence of the appropriate interactions at higher length scales. This confirms that already existing materials, which have been adequately characterized and studied, can prove to be a very useful source of information for the design of novel mechanical metamaterials which can exhibit even more auxetic properties than the original material itself.

放大的砷酸硼：一种增强的纳米模拟机械超材料

通过有限元模拟，介绍并研究了使用传统材料在宏观尺度上构建的受单晶砷酸硼启发的新型机械超材料。结果表明，这些机械超材料在某种程度上可以模仿砷酸硼的特性，更坚固的旋转刚性单元机制被很好地复制，甚至可以通过修改机械超材料的几何形状来更有效地运行。还表明，由于在较高长度尺度上缺乏适当的相互作用，并非所有在纳米尺度上引起拉胀的机制都可以放大。这证实了已经充分表征和研究的现有材料，
