This paper presents a comprehensive review on different theoretical elastic and viscoelastic
foundation models in oscillatory systems. The review covers the simplest foundation models …

Track transitions such as bridge approaches, road crossings and shifts from slab track to
ballasted track are common locations where track degradation accelerates due to dynamic …

Transition zones between structures as bridges or box culverts frequently present higher
degradation rates compared to the remaining railway. This paper presents a numerical …

A railway track–subgrade system is modeled using the finite element method (FEM). Two
different transition zones between a bridge and an ordinary subgrade, usually used for high …

Transition zones in railway tracks are the locations with considerable changes in supporting
structures. Because of the difference in the structures or material properties, the differential …

To guarantee the operation safety of the tram in typical soft soil area, the damage
characteristics of tram track slabs due to subgrade differential settlement, dynamic train …

This paper presents for the first time a closed-form solution of the dynamic response of
sigmoid bidirectional functionally graded (SBDFG) microbeams under moving harmonic …

A relatively recently developed method known as the moving element method (MEM) is
further extended to deal with moving loads that travel along inhomogeneous visco-elastic …

Transition zones such as level crossing and bridge approaches are critical links in railway
networks due to higher degradation rates and maintenance needs. In this context …

High-speed train induced vibrations of track structure and underlying soils differ from that
induced by low-speed train. Determining the critical speed of train operation remains difficult …
