Abstract
This paper verifies two laws for plastic flows of face-centered cubic crystals that deform at constant strain rates and fixed ambient temperatures. The first law relates steady-state flow stress to ambient temperature and strain rate. The second law requires an increase of configurational entropy towards a maximum reached in the steady state. The large scale least squares analysis is provided which allows the physics-based parameters of thermodynamic dislocation theory to be identified in accordance with these laws.
