摘　　要：根据疲劳裂纹扩展的规律，对等幅和变幅谱载下ＣＣＴ及ＰＳ（Ｔ）试件的疲劳裂纹扩展进行了计算机模拟。其结果经疲劳试验考评，误差在４０％以内，能满足疲劳分析的要求。According to characters of fatigue crack propagation,we imitated the tests of CCT and PS(T) by computer under constant amplitude and varied amplitude spectrum loading.The errors are about 40% after comparing the results of computer simulating and experiment test. It is possible that computer simulating may effectively take the place of fatigue crack propagation tests.
