The interfacial Stoneley waves at the Wiechert condition imposed on physical properties of the adjacent isotropic and homogeneous halfspaces are analyzed. It is shown both theoretically and numerically that the speed of propagation of Stoneley waves along the Wiechert line is a monotonically decreasing function of the dimensionless Wiechert parameter. It is also found that such a monotonic behavior takes place at the nonnegative values of Poisson’s ratio. The observed monotonic behavior delivers the unique possibility for applying acoustic methods to nondestructive evaluation of physical parameters of media satisfying the Wiechert condition.

斯通利在维切特条件下挥舞

分析了在Wiechert条件下施加于相邻各向同性和均质半空间的物理性质的界面斯通利波。理论上和数值上都表明，斯通利波沿Wiechert线的传播速度是无量纲Wiechert参数的单调递减函数。还发现这种单调行为发生在泊松比的非负值处。观察到的单调行为为将声学方法应用于满足Wiechert条件的介质物理参数的非破坏性评估提供了独特的可能性。
