Article Description

An analytical and numerical approach to the study of processes in a hydroelectroelastic spherical shell–acoustic layer system is proposed. The perturbed motion of the fluid and the shell is modeled by the relations of the acoustic approximation and theory of thin electroelastic shells. Using the method of image sources, the method of separation of variables, and the Laplace integral transform in the time coordinate, the problem is reduced to an infinite system of Volterra integral equations with arguments with a delay. The system is solved numerically using the method of reduction. The numerical results are given for the case of the perturbation of the shell as a point source by an electrical load in the form of a sinusoidal impulse.
