Acoustic Emission Characteristics of Plywood in Tensile Loading

  • 摘要: 针对传统的力学试验方法对胶合板破坏过程的表征不足,提出了用声发射检测技术全程监测胶合板拉伸破坏过程。试验表明,材料的损伤破坏具有阶段性,不同阶段的声发射信号特征有明显的区别。研究发现声发射特征参数能够表征材料受载过程中的损伤演化规律和损伤类型,能直观地反映材料的损伤特征。因此,声发射检测技术可作为材料测试、质量评定的有效手段,也是传统力学方法的有益补充。
    Abstract: Acoustic emission technique was used to monitor the failure process of plywood in tensile loading, which used a supplement method of the traditional mechanical testing. The test results showed that the damage process of material could be divided into several stages according to different characteristics of AE parameter. Furthermore, the research revealed that damage evolution mechanisms and damage modes could be characterized by AE characteristic parameters during tension process, which could reflect the damage characteristics of plywood. So it was expected that acoustic emission technique was a useful supplement for the traditional mechanical method in evaluating the material quality.
