Wave Propagation in Coating and its Laser Ultrasonic Testing

摘要: 建立了一个理论模型来预测激光激发涂层中的超声波传播，并利用傅里叶变换方法对声场的瞬态位移进行理论求解。计算结果显示，所设计模型能很好地预测激光在不同涂层中所激发的位移场，为进一步的试验验证和反问题求解提供理论依据。

Abstract: In this paper, a theoretical model was introduced to predict the propagation of ultrasonic waves excited by laser in a coating. The transient displacement of the acoustic field was solved by Fourier transform. The numerical results could predict the transient displacements for various coatings, and it could provide the theoretical guide for the experiment and inverse problem.
