　　uniaxial low cycle fatigue life estimation method is applied to multiaxial proportional loading in Von Mises equivalent strain method, which neglects the effects of strain paths phase angle to fatigue damage.A new life prediction model suitable for the multiaxial proportional loadings was put forward, this model take the effects of strain paths phase angle to fatigue damage into account, and the prediction precision is further improved.
