Free–Free Beam Resting on Tensionless Elastic Foundation Subjected to Patch Load
Mathematics, 2022 Despite the popularity of a completely free beam resting on a tensionless foundation in the construction industry, the existing bending analysis solutions are limited to certain types of loads (mostly point and uniformly distributed loads); these are ...

Rail Joint Model Based on the Euler-Bernoulli Beam Theory
Romanian Journal of Transport Infrastructure, 2019 In this paper, a rail joint model consisting of three Euler-Bernoulli beams connected via a Winkler foundation is proposed in order to point out the influence of the joint gap length upon the stiffness of the rail joint.

Free Vibrations of an Elastically Restrained Euler Beam Resting on a Movable Winkler Foundation
Shock and Vibration, 2019 The traditional theory of beam on elastic foundation implies a hypothesis that the elastic foundation is static with respect to the inertia reference frame, so it may not be applicable when the foundation is movable.

The contact separation of a finite beam from the tensionless Winkler foundation due to the force acting at the one beam end [PDF]
Tehnika, 2018 In this paper, bending of a finite beam, positioned on the elastic foundation of tensionless Winkler type, is analysed. Beam is subjected to the two different types of load, concentrated vertical force acting at the one end in combination with the ...

FROM WINKLER’S FOUNDATION TO POPOV’S FOUNDATION
Facta Universitatis, Series: Mechanical Engineering, 2019 In recent years, the method of dimensionality reduction (MDR) has started to figure as a very convenient tool for dealing with a wide class of elastic contact problems. The MDR modeling framework introduces an equivalent punch profile and a one-dimensional Winkler-type elastic foundation, called henceforth Popov’s foundation.

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 ...

Failure Processes in Embedded Monolayer Graphene under Axial Compression [PDF]
, 2016 Exfoliated monolayer graphene flakes were embedded in a polymer matrix and loaded under axial compression. By monitoring the shifts of the 2D Raman phonons of rectangular flakes of various sizes under load, the critical strain to failure was determined ...
