具有微极弹性构架的流体-饱和多孔固体中波在边界面处的传播

Wave Propagation in a Liquid-Saturated Porous Solid With Micropolar Elastic Skeleton at Boundary Surface

通过研究匀质非黏性液体半空间和微极流体饱和多孔固体半空间交界面处平面波的反射与透射,得到不同角度入射波的反射和透射系数.计算出反射波与透射波的振幅比数值,并用图表示出微极性和多孔性对反射和透射的影响.最后根据公式对一些特例进行了推导.

The reflection and transmission of plane waves at an interface between homogenous inviscid liquid half space and a micropolar liquid-saturated porous solid half space are studied. The reflection and transmission coefficients of various reflected and transmitted waves with the angle of incident were obtained. Numerical calculation were performed for amplitude ratios of variously reflected and transmitted waves. Micropolarity and porosity effects on the reflection and transmission coefficients were depicted graphically. Some particular cases were deduced from the present formulation.
