穿透及表面疲劳裂纹扩展的计算机模拟
Computer Simulating of Through or part-through Fatigue Crack Propagation
Abstract
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.
