本文描述了测试裂纹快速扩展速度的断裂丝棚法,采用记忆存贮示波器和计算机自动数据采集和记录系统以及采用自制的 GLC-1型高速裂纹扩展速度测试仪分别测试了300Mn 钢材料的动态裂纹扩展速度,结果吻合良好.
In this paper, the cracked wire shedding method for testing the rapid crack propagation is described. The dynamic crack of 300Mn steel is tested by memory storage oscilloscope and computer automatic data acquisition and recording system and by the homemade GLC-1 high speed crack propagation velocity tester Expansion speed, the result is in good agreement.
