Formation of Directed Wave Fields on Surface of Deformable Layer Under Impulse Load

The kinematic and energy characteristics of the viscoelastic layer under the action of the impulse load are calculated. The structure of the perturbed surface of the layer and its ability to absorb the energy of external impulse perturbations are estimated on the basis of the calculations. The conditions for maximum energy absorption of the impulse load are determined, depending on the duration of the load, local thickness, and mechanical parameters of the viscoelastic layer. Variability of the viscoelastic layer thickness allows controlling the wave structure of the perturbed surface and forming directed surface wave fields, in particular, to develop the effective methods of flow control using deformable surfaces.
