Axisymmetric Buckling of Reddy Circular Plates on Pasternak Foundation

Journal of Engineering Mechanics, 2001
Presented herein are the exact axisymmetric buckling solutions of Reddy circular plates on the Pasternak foundation and subjected to a uniform radial load. The boundary conditions of the circular plates covered in this study are (1) simply supported edges; (2) clamped edges; and (3) simply supported edges with elastic rotational restraints.

Free Vibrations of Beams on Viscoelastic Pasternak Foundations

Applied Mechanics and Materials, 2015
This paper investigates free transverse vibrations of finite Euler–Bernoulli beams resting on viscoelastic Pasternak foundations. The differential quadrature methods (DQ) are applied directly to the governing equations of the free vibrations. Under the simple supported boundary condition, the natural frequencies of the transverse vibrations are ...

Warping Stresses in Concrete Pavements on Pasternak Foundation

Journal of Transportation Engineering, 1993
This paper develops a solution of warping stresses in concrete pavement slabs resting on a Pasternak foundation. The solution is derived using the classical thin‐plate theory. Warping stresses in a slab of length A and width B is obtained by superposing the solution of a slab with length A and infinite width and that of a slab with width B and infinite

Buckling of Beams Supported by Pasternak Foundation

Journal of the Engineering Mechanics Division, 1973
The determination of buckling loads for infinitely long beams resting on a Pasternak (1954) foundation is considered. It is assumed that the onset of buckling takes place at neutral equilibrium. The effect of extending the foundation beyond the width of the beam is determined by comparing the results obtained for two- and three-dimensional foundations.

Steady-State Vibrations of a Beam on a Pasternak Foundation for Moving Loads

Journal of Applied Mechanics, 1980
The response of an infinite beam supported by a Pasternak-type foundation and subjected to a moving load is investigated. It is assumed that the load is uniformly distributed over the finite length on a beam and moves with constant velocity. The equations of motion based on the two-dimensional elastic theory are applied to a beam.
