Principle of virtual work andthe discontinuous Galerkin method

D'Alembert's principle, also known as the Lagrange–d'Alembert principle, is a statement of the fundamental classical laws of motion. It is named after its discoverer, the French physicist and mathematician Jean le Rond d'Alembert. It is the dynamic analogue to the principle of virtual work for applied forces in a static system and in fact is more general than Hamilton's principle, avoiding

Flexure of Thick Simply Supported Beam Using Trigonometric

Principle of virtual work in elasticity states that the work done by all the real "forces" (inertial, body forces, and tractions) in any virtual deformation of the body is zero. This is nothing but a weak form of balance of linear momentum and is widely used, for example, in finite element formulations.
