摘要:用声发射监测带有不同深度缺口的Q2 35钢试样的拉伸试验 ,由声发射信号分析判断缺口发生破坏的情况。缺口深度越大 ,声发射活动性越小 ,声发射事件振幅较小。缺口效应引起了声发射特性的变化。
The tensile test of Q235 steel samples with notches of different depths and their damages were monitored by acoustic emission technique. The deeper the notch was, the lower the activity of acoustic emission was, and the smaller the amplitudes of acoustic emission events became. Acoustic emission characteristics changed by notch effect.
