摘要

In the present paper the initial-boundary value problem Sor a thin viscoelastic plate with great deflections is formulated and studied. The system of the nonlinear pseudoparabolic and Volterra integro-differential equations for the deflection and the Airy stress function is formulated. The considered system represents a generalization of the the Dan Karman equations for the elastic case. The weak formulation in Sobolev spaces and the canonical initial value problem for the deflection function are investigated The existence of a solution is verified using elliptic regularization.
