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

准纵向位移波在两个非局部正交各向异性微极半空间之间的不完美界面处的反射和传输

这项工作涉及准纵向位移波入射在两个非局部正交各向异性微极半空间之间的不完美界面上的反射和传输。线性弹簧模型用于描述界面处键合行为的缺陷。当纵向位移波撞击不完美和完美界面时，波的反射、透射系数和能量比已经通过分析推导出来。最后，通过数值例子说明了不完美的界面、非局部参数和入射角对反射和透射系数的影响。
