Abstract
The coupled thermoviscoplasticiry equations for a thick-walled cylinder subjected to thermomechanical loading at the inner surface are presented and implemented in a finite-element program. The numerical solution for a steel cylinder subjected to a single traction and temperature pulse shows considerable temperature rise due to mechanical energy dissipation. The results also suggest a criterion for the yield stress in order to avoid failure due to excessive viscoplastic deformation at the inner surface.Keywords
