A. Blouza, EXISTENCE AND UNIQUENESS FOR NAGDHI MODEL FOR SHELLS WITH LITTLE REGULARITY, Comptes rendus de l'Academie des sciences. Serie 1, Mathematique, 324(7), 1997, pp. 839-844
We give a simple proof of existence and uniqueness for Nagdhi's model
for shells whose midsurface can have discontinuous curvatures. This im
proves earlier proofs by Ciarlet, Miara and Bernadou, and Ciarlet and
Miara for C-3-midsurfaces.
