Abstract

An interesting phenomenon observed in auxetics (materials with negative Poisson’s ratio) relates to appearing anomalous velocity intersections of the interfacial Stoneley waves at varying acoustic properties of the contacting media satisfying Wiechert condition. Comparative analysis with the non-auxetics (materials with positive Poisson’s ratio) revealed the absence of such intersections. The analysis is based on solving secular equation for Stoneley waves in the modified Scholte form.

拉胀剂和非拉胀剂中的斯通利波：Wiechert 案例

摘要

在拉胀剂（具有负泊松比的材料）中观察到的一个有趣现象与在满足 Wiechert 条件的接触介质的不同声学特性下出现界面斯通利波的异常速度交叉点有关。与非拉胀剂（具有正泊松比的材料）的比较分析表明不存在此类交叉点。该分析基于求解修正 Scholte 形式的斯通利波的长期方程。
