Abstract This study investigates the free vibrations of elastically constrained shear and Rayleigh beams placed on the Pasternak foundation. Of particular interest, it is aimed to analyze the influence of shear strain, rotational inertia, elastic stiffness, and shear layer on the natural frequencies and eigenmodes of beam vibrations. For

Large Deflection of a Rectangular Plate Resting on a Pasternak-Type Elastic Foundation
Journal of Applied Mechanics, 1977The 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, 2010The 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, 2011In 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, 2014Abstract 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 ...

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.

Composite Structures, 2011
Abstract In this study, the mechanical buckling of functionally graded material cylindrical shell that is embedded in an outer elastic medium and subjected to combined axial and radial compressive loads is investigated. The material properties are assumed to vary smoothly through the shell thickness according to a power law distribution of the volume

Vibration Analysis of Functionally Graded Timoshenko Beams on Winkler–Pasternak Elastic Foundation
Iranian Journal of Science and Technology, Transactions of Civil Engineering, 2019This 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.
