摘要：

We outline here a method for incorporating the scatter observed in creep rupture times and fatigue cycles-to-failure into a probabilistic model for creep-fatigue failure. We do this within the context of the well-known. damage fraction summation rule. Various numerical methods for calculating the probability of failure for given creep-fatigue loading cycles are discussed.
