摘要: Abstract Free vibration analysis of curved structural components such as truncated conical shells, circular cylindrical shells and annular plates has been investigated numerically in this paper. The method discrete singular convolution (DSC) the differential quadrature (DQ) are used for numerical simulations, respectively. Related partial equations governed motion structures obtained from higher-order shear deformation theory have solved by using these two methods space domain. Different material properties considered isotropic, laminated functionally graded (FGM). Four-parameter power law simple distributions ceramic volume fraction FGM cases. results related to free present techniques compare well with available literature. Results also presented different geometric parameters. effects grid number types distribution plate shells.
