Zur elastisch-plastischen Deformation drehsymmetrisch erhitzter Kreisscheiben (Q1085689)

It is shown that, based on Tresca's yield criterion, plastic deformation of a heated disk does not set in at the insulated edge. For plastic flow near the edge, the difference of circumferential and radial stress is essential. The borders of the plastic annular zone prove independent of the hardening law and can be determined directly from the temperature field. The stress distribution in the outer elastic region agrees with the one occurring for unrestricted elastic behaviour.
