On the vibration of an elastic plate on an elastic foundation

Journal of Sound and Vibration, 1967
This paper is a study of the vibration of an elastic plate under a time-harmonic point force. The plate is infinite in extent and rests on an elastic foundation. This study is made on the basis of the improved (Timoshenko) plate theory. The mathematical problem is to seek a fundamental solution of the time-reduced plate equation of the improved plate ...

Elastic-Plastic Slabs on Elastic Foundation

Journal of the Structural Division, 1978
A method of analysis and design of rectangular and circular elastoplastic, reinforced concrete, and slabs resting on a Winkler-type foundation is proposed in this paper. The method is an application of the yield-line theory of structures and gives upper bounds of the true limit loads.

Plates on Elastic Foundation

Journal of Structural Engineering, 1990
Analysis of rectangular plates resting on a Winkler-type, one-parameter foundation is studied. The finite element method is applied and a 12-degree-of-freedom, nonconforming rectangular plate element is adopted. Based on shape functions of the plate element, an energy approach is used to derive a closed-form, 12-by-12, consistent foundation stiffness ...

Elastic and Viscoelastic Foundation Models

Journal of Applied Mechanics, 1964
The present paper contains a critical study of a number of foundation models as well as a further development of some of the ideas involved. Among others it is shown that the Pasternak foundation is a mechanical model for the so-called “generalized” foundation.

Wave Propagation in an Elastic Beam or Plate on an Elastic Foundation

Journal of Applied Mechanics, 1962
Presented is an analysis of wave propagation in an infinite elastic plate or beam on an elastic foundation, based on a comparison of frequency spectra (or wave-train solutions) from the exact equations and existing approximate bending theories. A distinct similarity is found between the spectrum representing the more exact theory of bending and the ...

Beams on Variable Winkler Elastic Foundation

Journal of Applied Mechanics, 1986
A stiffness approach is presented for computing the solution of beams on variable Winkler foundation. The solution may be achieved using only a small number of elements along the beam. Accuracy is dependent only on a preset user criterion. A numerical example demonstrates the efficiency and accuracy of the procedure.

Nonlinear Dynamics of a Beam on Elastic Foundation

Nonlinear Dynamics, 1997
The nonlinear dynamics of a simply supported beam resting on a nonlinear spring bed with cubic stiffness is analyzed. The continuous differential operator describing the mathematical model of the system is discretized through the classical Galerkin procedure, and its nonlinear dynamic behavior is investgated using the method of normal forms.
