摘要
文章对过去50年笔者所涉及的一些声发射项目做了回顾。笔者的声发射生涯是从检验玻璃环氧树脂圆柱形压力容器的剩余强度开始的,然后很快地延伸到了其它的很多材料、制品和结构中去。笔者在文中会介绍尽量多的信息,诸如:非金属和金属压力容器、影响声发射的因素、变型模式的识别、降噪技术、地上储罐泄漏探测、结合AE与UT、木材颗粒板的声-超声检验、飞行中飞机结构的监测以及葡萄科植物的缺水探测等。
This paper has a description of some of the Acoustic Emission projects that I have been involved with during the past 50 years. While my career in AE started with determining the residual strength of a glass and epoxy composite cylindrical pressure vessel it quickly expanded into many different materials, products and structures. In this paper I present information on efforts in; non-metallic and metallic pressure vessels; factors effecting AE; identification of modes of deformation; noise rejection methods; leak detection in Above Ground Storage Tanks; combining AE with UT; Acousto-Ultrasonic examination of wood particle boards; in-flight monitoring of Aircraft structure; and determination of water stress in grape plants and others.
