Vibration of FG magneto-electro-viscoelastic porous nanobeams on visco-Pasternak foundation

Composites Part B: Engineering, 2018
In this paper, the size-dependent vibrational behaviors of functionally graded (FG) magneto-electro-viscoelastic nanobeams in the presence of porosities and embedded in the viscoelastic medium are studied based on the nonlocal Timoshenko beam theory in ...

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

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.

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.

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.
