| Abstract: | On the basis of the damage mechanics and probability, the variation of the bursting pressure of rupture discs in fatigue process was studied, the method and monograph for evaluating safety life of rupture discs were proposed. The photographs of the sweep electron microscope show that fatigue damage are caused mainly by microcracks and impurities of metal. |
