Existence of solutions to obstacle problems for Reissner's plate model

Abstract

Contact problems for geometrically linear andelastic plates were studied in one side, provided that friction is negligible for linear models such contact problems lead, in general, to nonconvex minimization problems. Existence theorems formula for plate models were considere. we are interested in the study of existence of weak solutions to obstacle contact problems for linear Reissner’s plate model

La formule des th´eor`emes d’existence pour les mod`eles de plaques a ´et´e consid´er´ee. nous nous int´eressons `a l’´etude de l’existence de solutions faibles aux probl`emes de contact d’obstacles pour le mod`ele de plaque de Reissner lin´eaire
