摘　　要：通过对试验中不同类型的轴拉试件进行数值模拟,对试验所得数据与模拟结果进行对比分析,证明了模型建立和参数选择的合理性。根据诱导缝周围应变发展情况,结合应力分布云图,判断诱导缝在荷载作用下的破坏过程,提出了切实有效诱导缝布置方式。The different types of axial tension specimens were simulated and the test results and simulate results were analyzed,then the models and parameters chozed in simulate procession were verified reasonable.According to the development of strain around induced joint, the damage procession of induced joint were judged combing with the stress contours, the effective layout of induced joint were proposed.

关 键 词：有限元分析 诱导缝 等效强度 裂缝扩展
