The probability fatigue life - span of pressure vessel under the action of different cycle load is closely related to the cycle load with high stress.

The thought of this paper is to discuss on and analysis to dynamic response of HSMS under impact load, and estimate its mean life based on noted stress fatigue design method.

Finally, this study analysised the asphalt mixture fatigue damage evolution process of stress control mode and established a relationship between unit load fatigue damage rate and the fatigue life.
