| Abstract: | Based on the principle of extensible-type semielliptical superficial cracks tend- ing to be "epuilibrium", this paper gives the classification of common semielliptical superficial cracks in engineering, and the curves through calculation. According to the types of initial cracks, certain fatigue life can be found from the curves, thus simplifying the calculation of fatigue life and bringing convenience to its practical usage in engineering. |
