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

Vibrations of an orthotropic shallow spherical shell on a Pasternak foundation

Composite Structures, 1995
Large amplitude free vibrations of a clamped polar orthotropic shallow spherical shell on a Pasternak foundation are investigated using Sinharay and Banerjee's approach. Numerical results are obtained for movable as well as immovable clamped edges.

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.

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.

Free vibrations of curved Timoshenko beams on Pasternak foundations

International Journal of Solids and Structures, 1990
Abstract A study of the natural vibration of a continuous Timoshenko curved beam on a Pasternak-type foundation is presented. The dynamic stiffness matrix of a curved member of constant section is derived. An example of a two-span curved beam is given to illustrate the application of the proposed method and to show the effects of flexural and ...

A Timoshenko-beam-on-Pasternak-foundation analogy for cylindrical shells

Journal of Sound and Vibration, 2003
Abstract A Timoshenko-beam-on-Pasternak-foundation model is developed for the analysis of thin elastic cylindrical shells. This model aims to bridge the gap between the Love–Kirchhoff theory and the approximate beam-on-elastic-foundation model of Vlasov (“long-wave” model), which accounts for only longitudinal stretching and circumferential bending ...

Nonlinear bending of shallow spherical shells on the Pasternak foundations

Applied Mathematics and Mechanics, 1991
Based on Karman's nonlinear fundamental differential equations, the new approach, which combines modified iteration method with Galerkin's one, has been put forward to solve nonlinear bending of shallow spherical shell with concave base and clamped edges on the Pasternak foundation under uniform loads in this paper.

Influence Surface Coefficients of Plates Resting on Pasternak Foundation

2022
In this study, internal force influence surface coefficients of plates resting on Pasternak foundation are obtained using the finite element method applying the classical Müller-Breslau Principle. The two-parameter elastic foundation is represented by the inclusion of the elastic bedding and shear parameter matrix terms of a 4-noded soil finite element
