About Central Difference Method Applied for the Beams on Elastic Foundation [PDF]

Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2013
This article is focused on the widely spread theory of straight and curved beams rested on elastic (Winkler's) foundation. For solution of these problems of mechanics, the Finite Difference Method (i.e. Central Difference Method) can be applied.

Study on Stability of Elastic Compression Bending Bar in Viscoelastic Medium

Applied Sciences, 2023
In the southeastern coastal regions of China, thick layers of marine soft soil are widely distributed, exhibiting characteristics such as high compressibility, high porosity, low strength, high sensitivity, and easy thixotropy, and these viscoelastic ...

On the validity of the method of reduction of dimensionality: area of contact, average interfacial separation and contact stiffness

, 2013
It has recently been suggested that many contact mechanics problems between solids can be accurately studied by mapping the problem on an effective one dimensional (1D) elastic foundation model. Using this 1D mapping we calculate the contact area and the

Nano and viscoelastic Beck's column on elastic foundation

, 2014
Beck's type column on Winkler type foundation is the subject of the present analysis. Instead of the Bernoulli-Euler model describing the rod, two generalized models will be adopted: Eringen non-local model corresponding to nano-rods and viscoelastic ...

Stability of Cracked Plates with Nonlinearly Variable Thickness Resting on Elastic Foundations

Journal of Materials and Engineering Structures, 2022
In this paper, the stability of rectangular cracked plates with nonlinearly variable thickness resting on the elastic foundations is studied. The thickness of the plate varies exponentially along the x-axis.

On micropolar elastic foundations

European Journal of Mechanics - A/Solids
The modelling of heterogeneous and architected materials poses a significant challenge, demanding advanced homogenisation techniques. However, the complexity of this task can be considerably simplified through the application of micropolar elasticity.

Determination of the Spring Constant for the Horizontal Movement of Rigid Rectangular Foundations Resting on Elastic Subsoil

Applied Sciences
In this paper, a formula for the spring constant Kx for the horizontal movement of rigid rectangular foundations resting on elastic subsoil and spring coefficient βx in this formula was derived, which demonstrates that βx depends on Poisson’s ratio ν. It
