The Principle of Virtual Work is reviewed in its relation to continuum mechanics. A formal three-dimensional proof is given for reference, and the principle is also stated in terms of generalized variables. Applications are given for general theorems such as uniqueness for specific media, for derivation of structural theories independently of material characteristics, and to numerical methods of finite element analysis.
