ON THE MOMENTUM OF ELASTIC WAVES AND ITS FORCE ON THE OBSTACLE
Gennady Denisov, Valery Novikov
It’s illustrated with simple examples that for the calculation of the momentum of waves and the force exerted by the wave reflected from an obstacle it is necessary to consider nonlinear factor in motion equations of elastic systems and in boundary conditions. It is shown that the method using concepts of “wave momentum” and “wave pressure” for solution this problems is unreasonable.
