| Abstract: | Nonlinear
dynamic analysis of circular plates on two parameter elastic foundations is
studied. Winkler and Pasternak models of elastic foundation are used. The
nonlinear partial differential equations obtained from von Karman’s large
deflection plate theory have been solved by using the discrete singular convolution (DSC) in
the space domain and the harmonic
differential quadrature (HDQ) method in the time domain. The influence
of stiffness of Winkler (K) and Pasternak (G) foundation on
geometrically nonlinear dynamic response of plates is investigated. The
influence of damping on the nonlinear dynamic response has also been studied.
Numerical results obtained by the application of present technique compare well
with the results available in literature |
