Abstract

Regions of existence for Stoneley waves are analyzed for the case when isotropic contacting media have different values of Poisson's ratios. The analysis is based on solving the secular equation in Scholte’s form for Stoneley wave velocity. It reveals substantial similarity in shapes of regions of existence at all studied values of Poisson's ratio pairs. A recently observed gap in regions of existence for media with equal Poisson’s ratios is also observed in cases when contacting media have different Poisson’s ratios including both auxetic and non-auxetic media.

拉胀和非拉胀介质中斯通利波的存在区域

摘要

对于各向同性接触介质具有不同泊松比值的情况，分析了斯通利波的存在区域。该分析基于求解斯科尔特形式的斯通利波速的长期方程。它揭示了在泊松比对的所有研究值下存在区域的形状有很大的相似性。在接触具有不同泊松比的介质（包括拉胀介质和非拉胀介质）的情况下，最近观察到具有相等泊松比的介质存在区域存在间隙。
