✦ Synopsis

A kinetic model is postulated which considers the interaction of cumulative fatigue damage and chance overload on a component or structure under typical probabilistic service load histories. This model recognizes that:

[I] materials fail from pre-existing flaws; [2] that flaws develop in a characteristic manner which is determined by the material properties, state and magnitude of the stresses at the flaw perimeter, the history of the imposed tractions, the thermal and environmental histories; and [3] the critical load for structural failure is a decreasing function of the crack length.
