摘要

A proof of Reissner's variational principle is given together with examples of its application. This principle allows an independent variation of displacements and stresses. The proof given is restricted to a small deformation. An expression was developed for the virtual work performed on an isotropic elastic body referred to Cartesian coordinates (x, y, z) with a Young's modulus E, a shear modulus G and a Poisson's ration NU loaded by external forces and subject to kinematic restrictions. Classical ordinary bending theory parameters were first obtained. A more general theory was then developed by adding Saint Venant displacements for torsion.
