Weighted Korn inequalities for thin-walled elastic structures
[Inégalités de Korn avec poids pour des structures élastiques de plaques minces]
Comptes Rendus. Mécanique, Volume 334 (2006) no. 12, pp. 707-712.

Des normes dans H1 avec poids appropriés sont présentées tels que l'inégalité du type Korn soit asymptotiquement exacte en ce qui concerne l'épaisseur et la rigidité des plaques élastiques. Les poids dépendent crucialement de la structure géométrique de la jonction des plaques.

Appropriate weighted norms in H1 are presented such that the Korn type inequality is asymptotically sharp with respect to relative thickness and stiffness of the elastic plates. The weights depend crucially on the geometric structure of the plates' junction.
