【Abstract】

<正>A new variational method is proposed to study the free vibration of stepped conical shells(SCSs) with classical and non-classical boundary conditions.Multilevel partition hierarchy,viz.,stepped SCS,shell segment and shell domain,is adopted to accommodate the computing requirements of high-order vibration frequencies. The prescribed-displacement boundaries are treated as special in-
