Краткое описание

The solution of the unsteady acousto-elasticity problem for the finite Timoshenko's plates is presented. The plate is assumed to occupy a part of an acoustically stiff baffle, covering a rectangular wave-guide of arbitrary cross-sectional dimensions (up to infinite extent). Provision is made for consideration of a finite field behind the obstacle. Two possible algorithms of the solution, based on reduction of the problem to various infinite systems of integro-differential equations, are developed. Applicability of the method of reduction to the infinite systems is justified. Several numerical experiments are performed in an effort to estimate both the error, caused by truncation of the infinite systems, and the rate of convergence of the iterative procedure of the solution. Reliability of the computational results is verified by comparison with the experimental data.
