    Abstract:
    The analytical/numerical matching (ANM) method was used to study acoustic scattering from an elastic cylindrical shell with axially-circumferential constraints. The effects of the interaction between the structural waves and the discontinuous constraints, and the effects of the resulting interaction on the resultant scattered sound field were analyzed. High-resolution local analytical solutions and low-resolution global numerical solutions were used to realistically model structural discontinuities. The ANM local solutions were derived to capture rapid system response to changes across the discontinuities constraint. The local solutions were combined with a smooth global solution and modeled by modal methods to obtain an accurate composite solution.
