摘要
在中等加载速率下,推导出对大理岩带垂直切口三点弯曲圆棒梁试件动应力强度因子的一般近似公式和断裂时的临界动应力强度因子的表达式。
The generable proximate formula of dynamic stress intercity factor of simple edge crack found bar specimen in three point bending of NanLing marble is gotten and the critical dynamic stress intensity factor of the specimen is also obtained in medium load ratio.
