| Abstract: | in this paper,the main idea of the reference[1]is widely applied to 3-D axisymmetric cracks,and SQCE fine element formulation for the stress,strain deformation field and stress streng factor of the cracks are firstly put forward. Large number of calculations and comprisions on typical examples are finished.New strength-calculating theory and method for shaft elements with symmetrical cracks are offered. |
