本文提出一种非密接界面模型,其中两个弹性固体被一个粘性流体薄膜所分开.按照粘性流体的摩擦定律计算了边界摩擦力,最后得到小入射角p波或SV波的,以及任意入射角SH波的反射系数与透射系数.当粘滞系数趋于无穷时,粘性界面模型的反射系数与透射系数退化为密接界面的相应结果,粘性界面模型的一个特点是当上下弹性体具有相同的波阻抗时,反射系数可以不为零.
In this paper, a non-intimate interface model is proposed in which two elastic solids are separated by a viscous fluid film, the boundary friction is calculated according to the friction law of the viscous fluid, and finally a small angle of incidence p or SV wave is obtained, SH wave reflection coefficient and transmission coefficient.When the viscosity coefficient tends to infinity, the viscous interface model of the reflection coefficient and the transmission coefficient degenerate to the corresponding results of the close interface, a characteristic of the viscous interface model is when the upper and lower elastomers have the same wave Impedance, the reflection coefficient may not be zero.
