| Abstract: | On the basis of Ref. 2], the influence of any size of the plates with a central crack on stress intensity factors (SIFs) is studies by the method of SQCE1] in this paper,and a large quantity of calculations are carried out. Based on the computation results,the 2-D size influence function of SIFs is fitted. From this, the problem of the calculation of SIFs for plates of any size with a central crack is solved. |
