Analysis of a Prestressed Sleeper for Railway Turnout under the Effect Static Load with a Unilateral Contact Model and Support Stiffness of Existing Railway Bed of a Railway Section in Vietnam

Journal of Materials and Engineering Structures, 2022
In the process of analyzing prestressed sleepers for turnout on elastic foundations with large lengths, authors around the world often use the one-stiffness model of Winkler or the two-stiffness model of the Filonenko-Borodich and Pasternak.

Nonlinear finite element formulation of the soil structure interaction through two parameter foundation model [PDF]

, 2010
The response of shallow and raft foundations is having a significant importance due to its complex behavior because of the semi-infinite soil media. Winkler\u27s model is the simplest model to deal with the structure and soil.

Mesh-free Dynamic Analyses of FGM Sandwich Plates Resting on A Pasternak Elastic Foundation

Mechanics of Advanced Composite Structures, 2017
This study analyzes the free vibration, forced vibration, resonance, and stress wave propagation of orthotropic sandwich plates made of functionally graded materials (FGMs). Dynamic analyses are conducted using a mesh-free method based on first-order shear deformation theory and the shape functions constructed using moving least squares approximation ...
