Abstract
In real processes involving large plastic deformations a major part of the stress power will be dissipated and involves thermodynamical changes that cannot be neglected. A framework for the description of thermoplastic processes based on the notion of isomorphic thermoelastic ranges is suggested. Within this framework, consistent flow and hardening rules as well as necessary and sufficient conditions for the second law to hold are derived for the rate‐independent case.
