Based on Phase Screen approximation, the reflection and transmission of ultrasonic waves from double random rough surfaces are investigated, and a model suitable for engineering applications to evaluate the signal loss of the wave propagating through double random rough surfaces for oblique incidence was set up. Because the phase correlation factor of the beam transmitting twice the rough surfaces was expressed into the function of flaw depth and incidence angle of beam, the model overcomes the...

Based on Phase Screen approximation, the reflection and transmission of ultrasonic waves from double random rough surfaces are investigated, and a model suitable for engineering applications to evaluate the signal loss of the wave propagating through double random rough surfaces for oblique incidence was set up. Because the phase correlation factor of the beam transmitting twice the rough surfaces was expressed into the function of flaw depth and incidence angle of beam, the model overcomes the limitation and inadequacy of conventional model, which uses only the phase screen approximation to evaluate the signal loss for oblique incidence. Theory is in well agreement with experiment results.

基于相屏近似理论 ,研究了随机双粗糙界面的超声波反射和透射 ,建立了声波斜射双粗糙界面的信号损失工程计算模型。模型中将两次通过粗糙界面的相位相关因子表达成深度及角度的函数 ,克服了以往单纯利用相屏近似进行单层粗糙界面的斜射双透射声波信号衰减计算的局限与不足。理论和实验吻合。

The calculation methods are presented for the reflection and transmission of ultrasonic waves incident from the fluid on to the arbitrary orientation interface of the general anisotropic solid. It is found that the reflection and transmission coefficients depend on, in general, the elastic parameters of the media, orientation of anisotropic solid surface and incident angle. The examples of numerical solution of the energy reflection and transmission coefficient are obtained for...

The calculation methods are presented for the reflection and transmission of ultrasonic waves incident from the fluid on to the arbitrary orientation interface of the general anisotropic solid. It is found that the reflection and transmission coefficients depend on, in general, the elastic parameters of the media, orientation of anisotropic solid surface and incident angle. The examples of numerical solution of the energy reflection and transmission coefficient are obtained for some anisotropic crystal and composite materials of different symmetry classes.
