Multilevel Nonuniform-Grid algorithm for Problems of Acoustic Scattering by Elastic Shells

The multilevel nonuniform-grid (MLNG) algorithm is adapted for solving problems of acoustic scattering by elastic shells immersed in a fluid and possibly filled with a different fluid. The scattering problem is formulated as a system of surface integro-differential equations in which the unknowns are the pressure and normal velocity distributions over the shell. Special cases of the problem are considered.
