Abstract
Covariance is imposed to the second law of thermodynamics and consequences are shown for elastic-perfectly-plastic bodies. In this setting, pointwise balances of standard and configurational actions, constitutive restrictions on the first Piola-Kirchhoff stress and the Eshelby one, and the structure of the dissipation are all derived from a unique source.
