A variational inequality is formulated to describe the contact of an elastic shallow shell with a rigid stamp. To solve the contact problem one has to minimize the shell energy functional on a convex closed set. This problem is equivalent to solve a variational inequality. The exact formulation of the problem is given in detailed form. The stamp reaction is characterized by two non-negative measures. Properties of these measures are analysed. The regularity of the solution is discussed.
