摘要

The finite element simulation method of high cycle fatigue(HCF) life scatter based on crystal plasticity theory was introduced. According to the features of microstructure of typical titanium alloy TC4, the grains model was established by Voronoi method. Combining the crystal plasticity constitutive equations of titanium alloy, the simulation of the effect of stress level on the fatigue life scatter was performed. The parameter of fatigue life dispersion was given. Results show that, the fatigue life is longer and the life is more dispersed as the loading decreases.
