| Abstract: | On the basis of analysising the status of the stress and stress variation of the elastic and plastic areas,the paper gave the suggestion of replacing the stress intensity factor by using the fracture stress and proved the practicability and advantages of it.It compiled the calculation program of the finite element in 3 dimensions and verified the suggestion combining with the calculated examples. |
