Acousto-Ultrasonic Testing Techniques
摘 要
声-超声技术用以评估弥散缺陷分布以及由此产生的材料力学性质变化，已成功应用于金属、复合材料、粘接结构和木材等的无损检测。综述了声-超声检测技术发展现状。在阐述声-超声技术基本思想的基础上，分析了声-超声检测系统的组成及影响检测结果的各种因素。重点讨论了传播模型研究中的自然模态和频散模态分析，以及信号处理方法中的应力波因子法、超声波衰减率法和统计分析法等。最后对声-超声技术进一步研究的关键技术进行了展望。

Abstract
As a method of assessing diffusing defects in materials and the variety of mechanical properties, acousto-ultrasonic techniques have been successfully used in the NDT of the composites, bonding and lumber. This paper provides an overview of the acousto-ultrasonic techniques. Based on the principle of the technique, the implementation and the influence factors were discussed. A few emphasis aspects included the natural modes and dispersion modes in academic analysis, stress wave factors, ultrasonic decay rate and the statistic analysis. In the end a conclusion and some challenging issues were proposed.
