Damped response of thin plates to step loads including geometric nonlinearity

摘要: This paper presents an approximate solution of the large deflection damped response thin isotropic circular and rectangular plates subjected to step loads. Simply-supported clamped with movable immovable inplane conditions are considered. Von Karman-type equations employed in terms transverse stress function. The is approximated by a one-term spatial shape function Galerkin's method used obtain differential equation for central deflection. solved Newmark-β scheme. Comparison available results has demonstrated that satisfactory engineering accuracy achieved present method.
