title = "Minimizing the sound radiated by a cylindrical shell",
abstract = "A cylindrical shell is optimized to reduce the sound it radiates. A finite-element model of a shell is created and coupled to an efficient boundary element model to estimate the total radiated sound power for a given harmonic excitation. The shell is harmonically excited at the center of a bulkhead located at the half-length of the shell. The element thicknesses are then altered using the GENESIS optimization software to minimize the sound power radiated by the cylinder. Two objective functions were used: namely surface velocity using the beta-method, and modal amplitude of structural-modes. Excellent sound power reduction was found for both cases.",
