The Free Energy Functional - Lesson 1

In this video, we talk about "variational principles," which are mathematical tools used in working with several physical phenomena that admit the notion of a state of equilibrium.

In this video, we'll apply variational principles to nonlinear elasticity. We will study the equilibrium of a deformable body in the form of work done by external forces, the internal energy of the system, and the Gibbs potential (or free energy).
