This paper carried out a study on partial stress-strain approach under uniaxial load and put forward reasonable calculation formula of damage.Taking the modified Neuber method as an example this paper explained its life estimation process.It also provided testing data of strain fatigue properties in low frequency for ten kinds of commonly used mechanical material made in our country.
