Abstract

A procedure for shakedown analysis in the presence of temperature-dependent elastic properties is proposed. It is based on a kinematic statement derived from a discretized version of the shakedown condition and provides an iterative method for the evaluation of the shakedown boundary. Strictly speaking, only upper bounds are obtained; however, the correct value is detected when the correct inadaptation modality is identified, which can be done in several practical situations, as some examples illustrate.
