In order to design high-performance roadways, a robust tool which can compute the structural response caused by moving vehicles is necessary. Therefore, this paper proposes a spectral element method-based model to accurately and effectively predict the 3D dynamic response of layered systems under a moving load. A layer spectral element and a...

In this work we propose a model for the analysis of the dynamic behaviour of a ballasted track that combines discrete and continuous elements. The rail is modelled via an Euler-Bernoulli beam, the periodically spaced sleepers are represented with lumped masses, and the ballast is simulated using a lattice (regular network of elastically...

Transition zones in railway tracks are areas with considerable variation of track properties (i.e., foundation stiffness) encountered near structures such as bridges and tunnels. Due to strong amplification of the response, transition zones require frequent maintenance. To better understand the underlying degradation mechanisms, a one...

Transition radiation is emitted when a source moves along a straight line with constant velocity and acts on or near an inhomogeneous medium [1,2]. Transition radiation occurs, for example, when a train crosses an inhomogeneity in the railway track, such as a transition in foundation stiffness. As the velocity of the trains becomes closer to the...

Transition radiation is emitted when a perturbation source (e.g., electric charge, mechanical load), which does not possess an inherent frequency, moves along a straight line at a constant velocity in or near an inhomogeneous medium. The phenomenon was described for the first time in electromagnetics, but it is universal from the physical point...

Ultrasonic inspection has become one of the most popular nondestructive testing technique because of its versatility and easy operation. It can detect internal cracks and inclusion type defects in homogeneous or layered materials, often without much difficulty. Layered materials, which are also called laminated materials, have become widely used...

A study of elastic wave motion in a dissipative medium, generated by surface forces is carried out in the present thesis. The main characteristic of the medium considered here, is that the dissipation of energy due to dynamic loads is not linearly proportional to the frequency. The purpose of this study is to describe the dynamic analysis of...

The analysis of structures subjected to fast moving loads is a subject of growing interest in railway and pavement engineering. The applications of transient analyses using finite element models, however, are still very limited. The faster a load moves the more elements we need to model the structure. Even at fast workstations and main frame...

This paper discusses the steady state response of a rigidly supported, granular layer to a moving load. Accordingly, the dynamic behaviour of a ballast layer under an instantaneous train axle passage is simulated, where the rigid support reflects a substratum that is much stiffer than the ballast layer, e.g. ballast in a concrete railway tunnel...

Steady-state vibrations of periodically supported structures under a moving load are analytically investigated. The following three structures are considered: an overhead power line for a train, a long suspended bridge and a railway track. The study is based on the application of so-called 'periodicity condition', which implies that the shape of...

Finite element models are usually presented as relations between lumped forces and discrete displacements. Mostly finite element models are found by the elaboration of the method of the virtual work - which is a special case of the Galerkin's variational principle -. By application of Galerkin's variational principle to time dependent problems,...
