| Abstract: | This paper took the extramicrosize of fracture as parameter variable, induced the basic equation which was suitable for the rate of breakage of various fracture's judgement, gave the information of the distributed functions of fracture size and the method of determining this function by simple experimental informations, and discussed the fatigue question of still and moving state of the application under the stress of multiaxis. Finally compared the theoretical informations and the experimental results. |
