The method for prediction of Paris' curve shape through the results of tensile test is suggested. For this purpose the author developed non-direct method for determination of Kth and Kfc and corresponding to them da/dN values. The relationship between Kth and b/y ratio was found. The correlation Kfc(KIc) was also shown. It makes possible to estimate lifetime of different structures with cracks under cyclic loading.
