弹性波作用下压电体摩擦接触界面滑移特性分析

弹性波与压电体摩擦接触界面相互作用会引起界面滑移或分离，滑移和分离位置的分布与外加压力、剪力、电场及入射波的条件有关。应用Fourier分析及matlab软件给出了滑移范围的解，给出了粘着、滑移或分离的判定条件，通过算例分析了滑移和分离出现的影响因素和条件，为工程应用提供了理论依据。

Slip Characteristic Analysis Of Frictional Contact Interfaces in Piezoelectric Materials When It Inteacted With Elastic Waves

Abstract: A question was studied primary on propagation of elastic waves through a contact interface between two piezoelectric solids. When the incident wave is strong enough, the contact interface will separate or slip in local interface areas, the extent and location of the separation and slip regions will vary with the external mechanical-electrical loads and the incedent wave. The solution of the slip regions are given theoretically by using Fourier analysis and Matlab software, and a method is developed to determine the condition that the separation、slip and stick region will be generated, and more the factor influencing the slip and sepration location are analyzed through an example.
