ABSTRACT

We present a new a posteriori error estimate for strongly heterogeneous elasticity problems. This new approach is based on a simple modification of the well known residual estimate, but with the nice property that it is correctly dimensionalised with respect to the physical data.

RÉSUMÉ

Dans ce travail on présente un nouvel estimateur d'erreur a posteriori pour des problèmes d'élasticité avec coefficients élastiques fortement hétérogènes. La nouvelle approche, qui est une variation de l'estimateur par résidu, a la propriété d'être correctement dimensionné par rapport aux données physiques.
