In this paper, the widely used two-layer model of the railway track is analysed with focus on the critical velocity and instability of moving masses. The model is assumed to be infinite …
In this paper, the steady-state response of a uniform infinite Euler-Bernoulli elastic beam resting on a Pasternak elastic foundation and subjected to a concentrated load moving at a …

The study analyzes the dynamic interaction of proximate masses using a new form of semi- analytical results for the moving mass problem developed by the author. This paper presents …
The present paper is concerned with the numerical modelization of the transient dynamic response of a simply supported Euler–Bernoulli elastic beam resting on a Winkler-type …
The rail pad is the elastic element between the rail and the sleeper that has the role of absorbing the mechanical stresses from the rail and reducing the vibrations and shocks …
Transition zones in railway tracks are areas with considerable variation of track properties (eg, foundation stiffness) which may cause strong amplification of the response, leading to …
