Décomposition des déplacements d'une poutre : simplification d'un problème d'élasticité

We present a decomposition of rod displacements. Then we use this decomposition to simplify an 3D linearized elasticity problem. The formal problem obtained is a differential system which depends on the thickness of the rod. We give error estimates. To cite this article: G. Griso, C. R. Mecanique 333 (2005).     

Une méthode inverse d'ordre un pour les problèmes de complétion de données

An iterative resolution method for inverse Cauchy problems is presented. The successive iterations satisfy the equilibrium equations exactly. Numerical simulations prove the accuracy of the method and its ability to solve Cauchy problems when the domain boundary is not regular. To cite this article: A. Cimetière et al., C. R.
