Natural Frequencies of Railway Slab on Winkler Foundation
Applied Mechanics and Materials, 2014Natural frequencies and natural modes represent the basic dynamic characteristics of all dynamic systems. They define the dynamic individuality of dynamic system. It is useful to know approximate relations giving the results with adequate accuracy. The analysis of plates in contact with elastic foundation is the part of structural dynamic which demands

Unilateral plate contact with the elastic-plastic winkler-type foundation
Computers & Structures, 1991Abstract In this work contact problems of a plate with the elastic-plastic Winkler-type foundation has been solved. An unilateral character of bonds between plate and foundation has been taken into consideration. The effect of friction forces in the contact plane has been neglected and an incremental approach has been applied.

Dynamic stability of a rectangular plate on non-homogeneous winkler foundation
Computers & Structures, 1997Summary: We study the dynamic stability of a rectangular plate on non-homogeneous foundation, subjected to uniform compressive in-plane bi-axial dynamic loads and supported on completely elastically restrained boundaries. The non-homogeneous foundation consists of two regions having different stiffnesses but symmetric about the centre lines of the ...

Stability and dynamics of beams on winkler elastic foundations
Earthquake Engineering & Structural Dynamics, 1989AbstractThe dynamical properties of a foundation beam on a Winkler soil have been recently discussed by using the power series method14 and the finite element method.15, 17 – 19 The first method can be applied only if the Winkler soil is linearly distributed along the whole span: on the contrary, the second method is more general, but it requires ...

A general solution to vibrations of beams on variable winkler elastic foundation
Computers & Structures, 1993A general solution to vibrations of beams on a variable Winkler elastic foundation is presented. The solution to the dynamic response of the beam is obtained by considering the reaction force of the foundation as the external force acting on the beam. This is described by an integral equation that includes the displacement of the beam.

NON-LINEAR VIBRATIONS OF A BEAM RESTING ON A TENSIONLESS WINKLER FOUNDATION
Journal of Sound and Vibration, 2000The forced vibrations of an elastic beam resting on a non-linear tensionless Winkler foundation subjected to a concentrated dynamic load at its centre are described in this paper. The problem is a non-linear one because of the tensionless character of the foundation and the non-linear term in the foundation model.
