Depleted uranium (DU) is a metal of very high mass density and, other than a few specialized uses, is treated as a waste product of the uranium enrichment process. To take advantage of its high mass density, we propose a novel application of this metal in elastic/seismic metamaterials. Such use can not only broaden the range of design possibilities for elastic metamaterials but can also give more meaning to the disposition of DU. Five different design concepts are modeled and analyzed using numerical techniques. The band structure comparison of the concepts shows that very low-frequency band gaps in the range of seismic wave frequencies can be achieved with very simple configurations, smaller geometries, and feasible placing arrangements.

贫铀（DU）是一种质量密度很高的金属，除少数特殊用途外，还被视为铀浓缩过程的废品。为了利用其高密度，我们提出了这种金属在弹性/地震超材料中的新应用。这样的使用不仅可以拓宽弹性超材料的设计可能性范围，而且可以为DU的配置赋予更多意义。使用数值技术对五个不同的设计概念进行了建模和分析。这些概念的频带结构比较表明，可以通过非常简单的配置，较小的几何形状以及可行的布置方式来实现地震波频率范围内的非常低的频带间隙。
