Predicting Remaining Life Using Damage Mechanics Principles

Continuum damage principles have been used to characterize damage occurring in pressurized components operating under creep conditions. Following a review of the concepts of damage and its measurement, analysis has been presented to show how damage can be estimated using continuum damage concepts and how the remaining life can be estimated in terms of the current creep rate of a component. It is shown how such damage can be estimated using measurements of the local creep rate.
