Résumé

We analyze the contact problem between two parallel thin linearly elastic plates under transverse loads. The initial distance between the two equal plates (both are clamped at the boundary) is equal to \( \delta \). The contact between the deformed plates is assumed to be elastic. The equilibrium problem is formulated in variational form via virtual work or, equivalently, in terms of minimum of the total energy. We use the mathematical framework of the theory of variational inequalities and we give different equivalent formulations of the non linear elastic problem introduced above. Finally, we obtain existence and uniqueness results.
