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KI的两种解法,而KII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。这两种方法具有简单方便的特点。
The two methods, Fourier calculus transtbrm and numerical resolution of finite elements, has been applied to resolve the stress intensity factor KⅠ of Fracture Mechanics. And KⅡ also should be obtained through the relations with KⅠ that resolution matches with others. The error＇s effect of the latter has been analysis and tested. Two methods are simple and convenient.
