摘　　要：提出Fourier积分变换和有限元数值解法求解工程断裂力学中应力强度因子KΙ的2种解法,而KΙΙ可通过两者之间的关系导出,其解值与实际均基本吻合;初步分析和验证了后者解析解的误差关系。这2种方法具有简单方便的特点。The two methods,Fourier calculus transform and numerical resolution of finite elements,have been applied to resolve the stress intensity factor K_Ι of fracture mechanics,and K_ΙΙ also should be obtained through the relations with K_Ι that result matches with others. The error's effect of the latter has been analysed and tested.The two methods have simple and convenient features.
