Web1 Apr 1994 · The elastic foundation (EF) is a Winkler-Pasternak’s model with two parameters consisting of Winkler-stiffness (k1) and Pasternak-stiffness (k2). The porosity distribution in plates is assumed to vary according to the even distribution (case 1) and uneven distribution (case 2) rules. The governing equation is derived from Hamilton's principle. WebThis paper hence extends the CS-FEM-DSG3 to dynamic responses of composite plates on the Pasternak foundation subjected to a moving mass. The composite plate-foundation system is modeled as a discretization of triangular plate elements supported by discrete springs at the nodal points representing the Pasternak foundation.
