【摘要】 对用奇异准谐调元（SQCE）理论进行疲劳裂纹扩展速率和剩余寿命的数值计算做了初步探讨，计算结果与实验结果完全吻合。因此，用SQCE理论计算实际结构的疲劳裂纹扩展速率和剩余寿命，可以达到节省时间、材料和经费的目的。更多还原

【Abstract】 This paper inquires into the calculation of the fatigue crack growth rate and surplus life by the Singular quasi-compatible finite element (SQCE) theory.The calculated results fits identically with the test results.Therefore,it may save time, materials and expenditure by calculating the fatigue crack growth rate and surplus life of structures by SQCE theory.更多还原
