摘要

本文研究了准P波入射在两个非局部横向各向同性弹性半空间之间的不完全界面上的反射和透射。采用线性弹簧模型来描述界面处键合行为的不完全性。导出了纵向位移波在非完美界面和完美界面入射时的反射透射系数。最后通过数值算例分析了界面不完全、非局部参数和入射角对反射系数和透射系数的影响。

Influence of boundary conditions on the reflection and transmission of qP-wave at an interface between two nonlocal transversely isotropic elastic half-spaces

Abstract This work is concerned with the reflection and transmission of quasi P wave incident at an imperfect interface between two nonlocal transversely isotropic elastic half-spaces. The linear spring model is used to describe the imperfection of bonding behavior at the interface. Reflection, transmission coefficients (RTC) have been derived analytically for when a longitudinal displacement wave strikes for both imperfect and perfect interface. Finally, numerical examples are provided to show the effect of the imperfect interface, nonlocal parameter and incident angle on the reflection and transmission coefficients.
