| Abstract: |
| The feasibility and completeness of isoparametric singular fracture finite element method have been analyzed.A series of new-type and high definition isoparametric singular fracture finite element have been constructed. The accuracy of the calculation method is demonstrated by comparison with other analytical or numerical solutions available in the literature. |
| Key words: finite element isoparametric singular fracture finite element basic function stress intensity factor |
