摘要
将声发射动态无损检测技术引入试件疲劳试验中,通过对试验过程中声发射信号的分析,获取试件的初始裂纹数据。证明声发射技术可以发现试验中试件的初始裂纹,并对其破坏具有预警作用。
Through studying acoustic emission signal in specimen fatigue tests,Found out the relation between the occur of crack and the acoustic emission events.Prove Acoustic Emission Technology can be use to discover the occur of the crack,and have a warning to the break of the specimen.
