Large Deflection of a Rectangular Plate Resting on a Pasternak-Type Elastic Foundation

Journal of Applied Mechanics, 1977
The problem of large deflection of a rectangular plate resting on a Pasternak-type foundation and subjected to a uniform lateral load has been investigated by utilizing the linearized equation of plates due to H. M. Berger. The solutions derived and based on the effect of the two base parameters have been carried to practical conclusions by presenting ...

Bending of thick functionally graded plates resting on Winkler–Pasternak elastic foundations

Mechanics of Composite Materials, 2010
The static response of simply supported functionally graded plates (FGP) subjected to a transverse uniform load (UL) or a sinusoidally distributed load (SL) and resting on an elastic foundation is examined by using a new hyperbolic displacement model. The present theory exactly satisfies the stress boundary conditions on the top and bottom surfaces of ...

Analysis of Circular Elastic Plate Resting on Pasternak Foundation by Strain Energy Approach

Geotechnical and Geological Engineering, 2011
In this paper, an analytical expression for the deflection of a thin circular elastic plate resting on the Pasternak foundation is derived by adopting the strain energy approach. The parametric study is carried out to observe the location of the plate lift-off and the variation of the deflection profiles for comparing the variation pattern reported in ...

Buckling analysis of magnetoelectroelastic plate resting on Pasternak elastic foundation

Mechanics Research Communications, 2014
Abstract Buckling analysis of magnetoelectroelastic plate resting on Pasternak foundation is investigated based on the Mindlin theory. The in-plane electric and magnetic fields can be ignored for magnetoelectroelastic plates. According to Maxwell equation and magnetoelectric boundary condition, the variation of electric and magnetic potentials along ...

An approach for the Pasternak elastic foundation parameters estimation of beams using simulated frequencies

Inverse Problems in Science and Engineering, 2017
AbstractAs a first attempt, a mix of differential quadrature (DQ) and simplex (S) method for the Pasternak elastic foundation parameters estimation of beams using simulated frequencies is presented. The method is applied for the parameters estimation of functionally graded (FG) beams.

Free vibration analysis of a magneto-electro-elastic doubly-curved shell resting on a Pasternak-type elastic foundation

Smart Materials and Structures, 2014
Free vibration of a simply-supported magneto-electro-elastic doubly-curved thin shell resting on a Pasternak foundation is investigated based on Donnell theory. The rotary inertia effect is considered in the formulation. Maxwell equations for electrostatics and magnetostatics are used to model the electric and magnetic behavior.

Benchmark solutions for functionally graded thick plates resting on Winkler–Pasternak elastic foundations

Composite Structures, 2008
Abstract Exact solutions for functionally graded thick plates are presented based on the three-dimensional theory of elasticity. The plate is assumed isotropic at any point, while material properties to vary exponentially through the thickness. The system of governing partial differential equations is reduced to an ordinary one about the thickness ...

Vibration Analysis of Functionally Graded Timoshenko Beams on Winkler–Pasternak Elastic Foundation

Iranian Journal of Science and Technology, Transactions of Civil Engineering, 2019
This paper aims to analyze dynamic response of axially functionally graded (FG) Timoshenko beams on Winkler–Pasternak elastic foundation. Spring constant and material inhomogeneity are used as research parameters in the dynamic analysis. In this study, ODEs in Laplace domain are calculated by using complementary functions method.
