摘要：
In engineering application a quantitative description of both fatigue and creep damage mechanisms is demanded for high-temperature alloy. The present work employs the cohesive zone model to numerically simulate the crack propagation in a nickel-based super-alloy. Effect of loading hold period is discussed. The comparison shows a reasonable agreement between numerical results and experimental observations.
