摘要
对弹性波在非均匀介质传播时的波幅进行了研究,用解析方法探讨了非均匀区域性质变化时对弹性波波幅的影响,将非均匀区域离散成薄层,建立了波动方程和波幅传递矩阵,通过数值计算结果与解析解的比较,为弹性波在工程中的应用提供了计算分析的依据。
Elastic wave transmission in a continuous inhomogeneous is studied. The wave transmission influence in inhomogeneous damaged zone is analyzed by dividing the inhomogeneous into layers and establishing the wave equation and transferring matrix of amplitude of waves. Then the study provides a basis for numerical analysis on engineering applying of wave by comparing the numerical results with the analytical results.
