Flexural waves at the edge of nonlocal elastic plate associated with the Pasternak foundation
Journal of Vibration and Control, 2022In this article, an elastic foundation is used to study the characteristics of flexural edge waves propagating on a piezoelectric structure. The nonlocal elasticity theory is introduced to investigate the microscale effect on edge wave propagation.

Circular plates on Pasternak elastic foundations
International Journal for Numerical and Analytical Methods in Geomechanics, 1987AbstractThis study deals with the geometrically nonlinear axisymmetric static and transient response of cylindrically orthotropic thin circular plates resting on Pasternak elastic foundations subjected to uniformly distributed loads. Clamped and simply‐supported plates with radially movable and immovable edges have been considered.

Ultimate Carrying Capacity of Elastic-Plastic Plates on a Pasternak Foundation
Journal of Applied Mechanics, 2014In the present work, the problem of an infinite elastic perfectly plastic plate under axisymmetrical loading conditions resting on a bilateral Pasternak elastic foundation is considered. The plate is assumed thin, thus making it possible to neglect the shear deformation according to the classical Kirchhoff theory. Yielding is governed by the Johansen's

Vibration Characteristics of Planar Curved Beams on Elastic Pasternak Foundations
2021—The objective of this study is to investigate the forced vibration analysis of a planar curved beam lying on elastic foundation by using the mixed finite element method. The finite element formulation is based on the Timoshenko beam theory. In order to solve the problems in frequency domain, the element matrices of two nodded curvilinear elements are ...

Advances in Applied Mathematics and Mechanics, 2021
Summary: In this paper, the vibration characteristics of beams with arbitrarily and continuously varying thickness and resting on Pasternak elastic foundations were analytically studied based on the elasticity theory directly. The general expression of stress function, which exactly satisfies the governing differential equations and the boundary ...

Thermodynamical Bending of FGM Sandwich Plates Resting on Pasternak’s Elastic Foundations
Advances in Applied Mathematics and Mechanics, 2015AbstractThe analysis of thermoelastic deformations of a simply supported functionally graded material (FGM) sandwich plates subjected to a time harmonic sinusoidal temperature field on the top surface and varying through-the-thickness is illustrated in this paper. The FGM sandwich plates are assumed to be made of three layers and resting on Pasternak’s

Clamped Plates on Pasternak-Type Elastic Foundation by the Boundary Element Method
Journal of Applied Mechanics, 1986A boundary element solution is developed for the analysis of thin elastic clamped plates of any shape resting on a Pasternak-type elastic foundation. The plate may have holes and it is subjected to concentrated loads, line loads, and distributed loads. The analysis is complete, i.e., deflections, stress resultants, subgrade reactions, and reactions on ...

Vibrations of an Euler-Bernoulli Nanobeam on a Winkler/Pasternak-Type Elastic Foundation
2018 IEEE 13th Annual International Conference on Nano/Micro Engineered and Molecular Systems (NEMS), 2018A non-local Euler-Bernoulli nanobeam theory is used to calculate free vibrations for a beam resting on a Winkler/Pasternak-type elastic foundation. On using Hamilton's Principle, the nonlinear equation of motion, which includes terms for stretching of the neutral axis, is derived. The Adomian modified decomposition method is applied to solve the fourth-

Thermal posybuckling of rectangular plates on pasternak elastic foundations
Mechanics Research Communications, 1988Thermal postbuckling of thin plates has not been studied extensively. Axisymmetric thermal postbuckling of circular plates and doubly-symmetric thermal postbuckling of square plates on Winkler foundations have been investigated by \textit{K. K. Raju} and \textit{G. V. Rao} [Comput. Struct.
