摘要：用声发射监测16MnR带预制中心穿透裂纹试板的拉伸试验，以声发射信号分析预制裂纹的运动。与裂纹失稳扩展相应的声发射事件信号参数值差异很大，反映了其显微断裂机制的不同。
The tensile test of 16MnR steel strip notched specimen was monitored by means of acoustic emission .the crack propagation was analyzed according the signals of acoustic emission. It was found that the signal parameters of acoustic emission events during the crack propagation were significantly different,which reflected different mechanism of microfracture.
