摘要
用声发射对低强度材料LD31铝材和A3钢双疲劳裂纹扩展过程进行了监测,得到了声发射参数与裂纹扩展速率的对应关系。介绍利用后处理线定位参数调整及载荷滤波降低噪声的具体方法。
Acoustic emission (AE) characteristics of the propagations of fatigue cracks in low strength materials are monitored and the relation between AE and crack propagation rate is discussed. Also given is the method for eliminating noise.
