Principles of Non-Equilibrium
Thermodynamics and Friction
In the preceding chapter we discussed mechanical foundations of vibra-
tions, stability, and self-organization. Here we will introduce the principles
of reversible and irreversible thermodynamics that are of relevance to fric-
tion-induced self-organization. In particular, we will discuss the entropic
stability criterion. In addition to the degrees of freedom that participate
in the mechanical motion and are studied by mechanics, physical objects
also have internal degrees of freedom. These degrees of freedom contain
thermal energy that, under certain circumstances, can be exchanged with ...
