On a thermodynamic foundation of Eyring rate theory for plastic deformation of polymer solids

The plastic deformation of almost all solid polymers can be represented by a thermally activated rate process involving the motion of cooperative mobile elements over potential barriers, based on the Eyring activated rate theory. The present study shows that the governing equations for the Eyring rate theory can be completely derived based on the principle of microscopic reversibility in the framework of non-equilibrium dynamics.

Automated summary

The plastic deformation of solid polymers can be effectively explained by the Eyring activated rate theory, which involves the movement of cooperative mobile elements over potential barriers. The current study demonstrates that the governing equations for the Eyring rate theory can be derived through the principle of microscopic reversibility in the context of non-equilibrium dynamics.
