The two fundamental variational theorems of solid mechanics are the principles of virtual work and complementary virtual work. Important corollaries to these theorems, the principles of stationary potential and complementary energies, respectively, were derived in Chapter 2 based on the existence of appropriate potentials for the forces. Further useful corollaries will be presented in this chapter. These additional variational and energy principles are usually considered to be the classical energy techniques for practical problem solving in solid mechanics.
