Solvability of a dynamic rational contact with limited interpenetration for viscoelastic plates

The solvability of the rational contact with limited interpenetration of different kind of viscolastic plates is proved. The biharmonic plates, von K'arm'an plates, Reissner-Mindlin plates and full von K'arm'an systems are treated. The viscoelasticity can have the classical (``short memory’') form or the form of a certain singular memory. For all models some convergence of the solutions to the solutions of the Signorini contact is proved provided the thickness of the interpenetration tends to zero.
