摘要
利用矩阵方法,本文提出了声波从具有刚性联接和滑移界面的层状固体媒质反射特性的一般模型,导出了包含一个或两个滑移界面的层状固体媒质纵波和横波声反射系数解析表达式。文中还给出一些典型粘接件声反射系数的数值计算结果,为正确选择超声评价这些界面特性所采用的技术参数提供了依据。
In this paper, a genernal model on sound reflection from a layered solid medium with rigid and slip interfaces that uses matrix method is proposed. Analytical expressions for reflection coefficients of both longitudinal and transverse waves from the layered solid medium with one or two slip interfaces are derived. Numerical results of sound reflection coefficients from some typical adhesive joints with slip interfaces, which may be useful for correct choice of technical parameters in ultrasonic evaluation of their interface features, are presented.
