Another approach to linear shell theory and a new proof of Korn's inequality on a surface
Philippe G. Ciarlet, Liliana Gratie · Comptes Rendus Mathématique · 2005
We propose a new approach to the quadratic minimization problems arising in Koiter's linear shell theory. The novelty consists in considering the linearized change of metric and change of curvature tensors as the new unknowns, instead of the displacement vector field as is customary. This approach also provides a new proof of Korn's inequality on a surface.
