| Abstract: | Failure models and fatigue life of composite pressure vessels with titanic lined and carbon fiber overwrapped were introduced breifly.Based on stress and strain data resulted from finite element analysis,the low cycle fatigue life and the reliability,which associated with stress rupture failure,of a real helium tank were presented in details.A qualification test demonstration of the helium tank's reliability applicable to the propulsion subsystem of satellites was identified as well. |
