INELASTIC DEFORMATION AND RUPTURE UNDER SEVERE THERMAL LOADING

This paper represents a review of the numerical procedures for the determination of elastic and plastic shakedown limits that have been developed during the past ten years. The general features of the predicted component response are described. which result in representations of the structural phenomena that are suitable for use directly in design. It is demonstrated how these basic calculations can be used to provide a measure of the strain accumulated for rare excursions beyond shakedown and when the component operates in the creep range. Procedures for dealing with creep rupture are also briefly described.
