摘要
详细描述了作者最近提出的一种新的复合型疲劳裂纹扩展的数值模拟技术,扼要介绍了两个常用的近似分析模型。通过对受单轴循环载荷作用的中心斜裂纹板的疲劳扩展分析,对两个常用的近似分析模型进行了评价。
A new numerical simulation technique of mixed mode fatigue crack growth proposed by the authors was described in detail.Two commonly used approximate analysis models were briefly introduced.In addition,an evaluation for the two commonly used approximate analysismodels was made by carrying out the fatigue growth analysis of an inclined crack in uniaxialcyclic loading plates.
