Applicability of a Three-Layer Model for the Dynamic Analysis of Ballasted Railway Tracks

Applicability of a Three-Layer Model for the Dynamic Analysis of Ballasted Railway Tracks

In this paper, the three-layer model of ballasted railway track with discrete supports is analyzed to access its applicability. The model is referred as <i>the discrete support model</i> and abbreviated by DSM. For calibration, a 3D finite element (FE) model is created and validated by e...
