Equilibrated tractions for the Hybrid High-Order method
[Tractions équilibrées pour la méthode hybride d'ordre élevé]
Comptes Rendus. Mathématique, Tome 353 (2015) no. 3, pp. 279-282.

Nous montrons comment obtenir des tractions de face équilibrées pour la méthode hybride d'ordre élevé pour l'élasticité linéaire récemment introduite dans [1] et prouvons que ces tractions convergent de manière optimale.

We show how to recover equilibrated face tractions for the Hybrid High-Order method for linear elasticity recently introduced in [1], and prove that these tractions are optimally convergent.
