Clamped Plates on Pasternak-Type Elastic Foundation by the Boundary Element Method

Journal of Applied Mechanics, 1986
A 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 ...

Vibrational analysis of curved single-walled carbon nanotube on a Pasternak elastic foundation

Advances in Engineering Software, 2012
Continuum mechanics and an elastic beam model were employed in the nonlinear force vibrational analysis of an embedded, curved, single-walled carbon nanotube. The analysis considered the effects of the curvature or waviness and midplane stretching of the nanotube on the nonlinear frequency.

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 ...

Thermal posybuckling of rectangular plates on pasternak elastic foundations

Mechanics Research Communications, 1988
Thermal 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.

Circular Elastic Plate Resting on Tensionless Pasternak Foundation

Journal of Engineering Mechanics, 2004
In this technical note, a thin circular plate resting on a two-parameter (Pasternak-type) foundation is studied under concentrated central and distributed loads. The governing equations of the plate are derived for static loading case considering the lift off (uplift) of the plate from the foundation.

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 ...

Thermomechanical bending response of FGM thick plates resting on Winkler-Pasternak elastic foundations

Steel & Composite structures, 2013
The present work deals with the thermomechanical bending response of functionally graded plates resting on Winkler-Pasternak elastic foundations. Theoretical formulations are based on a recently developed refined trigonometric shear deformation theory (RTSDT).

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 ...

Flexural waves at the edge of nonlocal elastic plate associated with the Pasternak foundation

Journal of Vibration and Control, 2022
In 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.
