Abstract

The up and down method to determine the detail fatigue rating (DFR) with experimentation was presented, which provides a more efficient way for DFR testing. By numerical simulation, the half-sample maximum likelihood estimation method was proved to be effective to gain the mean value of fatigue strength. But it must be modified when used to estimate the standard deviation. The confidence degree was ensured by the least amount of specimen. The expression of DFR acquired by the up and down method was given.
