A numerical design tool is presented for minimizing radiated sound power from a vibrating shell structure using a material tailoring approach. A finite element method using shell elements is used to predict the vibration response of the shell. The sound power generated by the shell under a harmonic

The paper presents a computational investigation on the effects of subtended and vertex angles on the free vibration characteristics of open conical shell panels. Unlike the conventional approximation using a rectangular or cylindrical co-ordinate system, this analysis adopts a natural conical co-or
