Scattered acoustic pressure fields are obtained when a free-flooded cylindrical shell of finite length is subjected to plane waves incident obliquely to the axis of the cylindrical shell. Integral equations are formulated for the cases of a rigid thin shell and a elastic thin shell with simply supported boundary condition at both ends. Equations are solved by a Rayleigh--Ritz type approach. Near-field and far-field acoustic pressures of the scattered sound are calculated. Scattered far-field acoustic pressures for a short shell and a long shell are discussed.
