    Graduate strain:thermodynamic force, stress:state variable. true/false?

    The mechanics of materials literature considers micro-structural damage to be a thermodynamic variable conjugate to strain energy release rate, not strain, not stress. The Gibbs energy density is defined as \begin{equation} \chi = \rho^{-1} \sigma : \epsilon - \psi \end{equation} where...
