TI  - FE Analysis of FGM Plates on Arbitrarily Orthotropic
Pasternak Foundations for Membrane Effects
AB  - In this study, the finite element analysis of sigmoid functionally graded material (S-FGM)
plates resting on orthotropic Pasternak elastic foundations with different material angles is
presented. For modelling, SAP2000 software package is used in which the required
adjustments are made to obtain the expected behaviour of the plate-foundation system. The
plate is modelled using both solid elements and layered shell elements by defining a
number of solid elements and layers in the thickness direction having elastic properties
equivalent to the properties of the S-FGM plate. The interaction between the plate and the
foundation is provided by equalizing the vertical displacements of the plate and foundation
nodal points. The orthotropic Pasternak foundation is modelled using plane strain elements
with some adjustments to the elastic properties. The membrane effects of the simply
supported S-FGM plate on Pasternak foundation are considered by defining the edge
boundaries of the system as pinned supports. These effects are excluded by converting all
boundary nodes into roller supports except for one of the corner nodes of the plate and the
foundation due to the stability requirement. A number of verification examples are
performed to demonstrate the convenience and robustness of the proposed model. This
work can be easily extended to static and dynamic analyses of FGM plates with various
geometries resting on arbitrarily orthotropic Pasternak elastic foundations for further
studies.
