REFLECTION OF SIMPLE WAVES IN ELASTIC HALF SPACE
-
摘要: 本文研究弹性体内中心简单波的特征平面和广义特征线。并利用特征线方法求解中心简单波在自由界面上的反射,得到了中心无旋波和中心等容波速度分量的边界放大系数及其某些数值结果。Abstract: In this paper the generalized characteristic of centered simple wave in elastic body is studied. Then characteristic method is employd to solve the wave reflection at boundary of half space. Reflection coefficients and amplifications of velocity components of P-wave and S-wave are expressed in close form and their three-dimensional diagrams are also given.
