| Abstract: | Taking I-type crack in three-point bending test piece as an example, this paper conducts the introduction and analysis of the use of finite element software ANSYS calculation of stress intensity factor approach. It obtained through the stress intensity factor values with the analytic solution of the comparison, showing that the finite element method using the stress intensity factor has a very high precision, and easy to use. |
