位于弹性半空间上的理想流体层动力反应——平面SV波入射

DYNAMIC RESPONSE OF IDEAL FLUID LAYER OVERLYING ELASTIC HALF-SPACE DUE TO SV WAVE INCIDENCE

根据弹性固体与理想流体动力学方程,导出了固-液介质交界面上波的透射与反射系数的理论公式,分析了平面SV波从弹性半空间入射到与理想流体层的交界面时,弹性半空间的弹性模量和密度,平面SV波的入射角和频率,以及流体的体积模量和密度对理想流体层动压力的影响。

Based on the wave equations of elastic solid and ideal fluid, theoretical formulas are derived for determining the refraction and reflection coefficients due to SV wave incidence from elastic half-space to the solid-fluid interface. With the formulas, the effects of the elastic modulus and density of the elastic medium, the incident angle and frequency of the incident SV waves, and the bulk and density of the fluid on dynamic pressures in the fluid are analyzed by numerical examples.
