摘要

得到了简谐波在具有Kelvin模型黏弹性介质中的外行扩散波与内行入射波应力场表达式。将波动在介质中的传播分为外行扩散波与内行入射波两部分，先得到简谐波在弹性介质中波动传播时外行扩散波与内行入射波各自的应力场，结合弹性波理论与黏弹性理论，分别得到了波动在Kelvin模型黏弹性介质中外行扩散波与内行入射波两部分的应力场，并将外行扩散波与内行入射波两部分的应力场分别表示为外行扩散波与内行入射波位移与速度场的表达式，其结果有利于波动理论在黏弹性介质中的应用

Abstract

The diffusion wave and incident wave stress fields of simple harmonic wave propagation in viscoelastic media with Kelvin model are presented. The propagating wave is divided into two parts of diffusion wave and incident wave. The diffusion wave and incident wave stress fields in elastic media are deduced firstly. Then the diffusion wave and incident wave stress fields in viscoelastic media with Kelvin model are presented combining elastic wave theory and viscoelastic theory. And the deduced stress fields can be expressed with the displacement and velocity expressions of diffusion wave and incident wave. The results are propitious for application of wave theory to viscoelastic media
