Covariance in plasticity

Abstract

Covariance is imposed to the second law of thermodynamics and consequences are shown for elasticperfectly 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. © 2013 The Author(s) Published by the Royal Society.
