This chapter presents formulations for the free energy attributed to elastic strains and geometrically necessary dislocations of a cubic (primitive) crystal. Proposing a consistent thermodynamical framework, field equations are derived, starting from the Clausius-Planck inequality. Thereby, energy dissipation due to dislocation motion is introduced in a thermodynamically consistent way. Finally, different flow rules for the slip systems are presented and discussed with regard to the thermodynamic consequences. |
