Abstract
Dynamic stability of a lattice viscoelastic plates interacting with a flow of ideal incompressible fluid is investigated. Stability of oscillations of viscoelastic elements of channel walls is investigated too. For the deflection function of the plates, oscillation equations are derived and sufficient stability conditions of its solutions are obtained. These conditions have the form of restrictions on the kernels of relaxation on the uniform flow velocity and other parameters of the considered mechanics system.
