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.
