摘要：
Using the Bodner-Partom model of viscoplastic flow and the finite-element method, we develop an approach to studying the process of reconditioning hollow parts of machines by thermoplastic deformation. A part yields plastically under the action of localized mobile heat sources. The process variables are optimized considering the stress intensity and temperature restrictions. We discuss process-related recommendations to lower the time-dependent and residual stresses. © 1999 Kluwer Academic/Plenum Publishers.
