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.

A boundary element formulation for a Reissner plate on a Pasternak foundation

Computers and Structures, 1999
Summary: We employ a boundary element formulation for a Reissner plate on a Pasternak foundation in order to derive complete expressions for internal point kernels. Quadratic isoparametric boundary elements are used to discretise the plate boundary. An efficient arrangement of the boundary element system matrices is discussed, and several examples are ...

THE PASTERNAK FOUNDATION An Attractive Alternative for the Winkler Foundation

Proceedings of the International Conference on Concrete Pavements
In this paper the Pasternak Foundation model is described. In this two parameter model the reaction of the foundation is determined by a vertical spring constant k (the modulus of subgrade reaction in the Winkler Foundation) in combination with a parameter k0 which can be seen as a horizontal linkage of the vertical springs (comparable to the function ...

Use of Pasternak Foundation Model in Concrete Pavement Analysis

Journal of Transportation Engineering, 1996
This paper examines the use of Pasternak foundation model in the analysis of load-induced concrete pavement deflections and bending stresses, as well as thermal stresses caused by warping of slabs. Using theoretical solutions developed by the authors for structural responses of slabs supported on Pasternak foundation, predicted slab deflections and ...

Vibrations of continuous Timoshenko beams on Winkler-Pasternak foundations

Journal of Sound and Vibration, 1978
Abstract The dynamic analysis of continuous Timoshenko beams on Winkler-Pasternak foundations by means of the general dynamic slope-deflection equations is presented. A three-span continuous beam on a Winkler-Pasternak foundation subjected to free and forced vibrations is used to illustrate the application of the proposed method and to show the ...

Large deflection analysis of cylindrical shells on a pasternak foundation

International Journal of Pressure Vessels and Piping, 1993
Abstract Nonlinear static analysis of a cylindrical shell on a Pasternak foundation is carried out using a new approach due to Sinharay and Banerjee. This approach involves the use of variational principles and Galerkin's techniques. The effect of geometric, material and foundation parameters on load-deflection characteristics in investigated for ...

Rectangular Thick Plate with Free Edges on Pasternak Foundation

Journal of Engineering Mechanics, 1994
In this paper the work on the thick‐plate equations and their solution for the problem concerning the bending of a rectangular plate with four free edges resting on the Pasternak foundation are described. The basic equations are those obtained from Reissner's 1945 theory, and are modified to include the Pasternak foundation.

Dynamic response of a Timoshenko beam on a tensionless Pasternak foundation

Structural Engineering and Mechanics, 2011
The dynamic response of a Timoshenko beam on a tensionless Pasternak foundation is investigated by assuming that the beam is subjected to a concentrated harmonic load at its middle. This action results in the creation of lift-off regions between the beam and the foundation that effect the character of the response. Although small displacements for the

The large deflection of an orthotropic cylindrical shell on a Pasternak foundation

Composite Structures, 1995
Abstract An orthotropic shallow cylindrical shell lying on a Pasternak type elastic foundation is investigated. Load/deflection curves are drawn for simply supported movable and immovable edge conditions. The influences of shell geometry, foundation parameters and edge conditions on these characteristics are discussed.
