在本文中，我们回顾了弱非线性介质和超材料中弹性波传播的分析、实验探索和应用的最新进展。我们提供了详细的技术讨论，概述了活跃研究的两个广泛领域：（1）离散非线性周期系统和超材料，以及（2）专注于非线性导波的连续非线性系统。具体目的是向读者介绍当前研究领域中使用的渐近分析方法，突出其迄今为止的结果，并激发后续研究。在适当的情况下，我们会提供有关实验探索和设想应用的详细信息，迄今为止，这两者都受到相对较少的关注。
In this paper we review recent progress on the analysis, experimental exploration, and application of elastic wave propagation in weakly nonlinear media and metamaterials. We provide a detailed technical discussion overviewing two broad areas of active research: (1) discrete nonlinear periodic systems and metamaterials, and (2) continuous nonlinear systems with a focus on nonlinear guided waves. The specific intent is to introduce the reader to asymptotic analysis methods currently being employed in the field of study, to highlight their results to date, and to motivate follow-on studies. Where appropriate, we include details on experimental explorations and envisioned applications, both of which have received relatively sparse attention to date.
