Reliability Model of Fatigue Damage Evolvement of Semi-Rigid Road Base Material
The fatigue damage evolving model of brittle materials for one-dimension stress status, as the critical damage DC unequal to 1, was established with damage mechanics theory. And also a new fatigue damage evolving reliability model was established based on the supposition of the fatigue life obeying the normal distribution, which was verified by fatigue experiments taking the semi-rigid base material for example, and the propagate life can be ignored. The value of damage variable Dp corresponding to any given probability p can be effectively calculated, the results show that D was a random variable, the method that to determine the damage of materials and to estimate the security of structures with the damage value D calculated by traditional determinate damage evolving model may cause a mistake that the damage could be evaluated out as a much smaller value and the potential danger of structures could be completely covered up.
