| Abstract: | This paper deduces the classical theory of thin plate bending from the generalized variational principles of the tree type variables which belongs to the tridimensional theory of elasticity, thusproving the agreement on energy principles between the accurate theory of elasticity and the proximal classical of thin plate bending. |
