The Behaviour of Under-Sleeper Pads at Switches and Crossings (S&C) - field measurements
Major growth in rail traffic in many parts of the world in recent years has brought railway networks close to capacity and restricted the time available for track access to carry out maintenance work without costly temporary route closures. There are, therefore, significant benefits in designing or modifying ballasted track systems to reduce maintenance and associated access requirements. Under...
متن کاملDiscrete Element Modelling Using a Parallelised Physics Engine
Discrete Element Modelling (DEM) is a technique used widely throughout science and engineering. It offers a convenient method with which to numerically simulate a system prone to developing discontinuities within its structure. Often the technique gets overlooked as designing and implementing a model on a scale large enough to be worthwhile can be both time consuming and require specialist prog...
متن کاملNumerical simulation of particulate materials using discrete element modelling
Discrete element method (DEM) is a numerical technique pioneered by Cundall for problems in rock mechanics where the continuity between the separate elements does not exist. Discrete numerical simulations with particles are currently used in several different scientific disciplines. The DEM is capable of handling a wide range of material behaviour, inter-body interaction force laws and arbitrar...
متن کاملCalibration of the Discrete Element Method Using a Large Shear Box
One of the main challenges in using the Discrete Element Method (DEM) is to specify the correct input parameter values. In general, the models are sensitive to the input parameter values and accurate results can only be achieved if the correct values are specified. For the linear contact model, micro-parameters such as the particle density, stiffness, coefficient of friction, as well as the par...
متن کاملA Study of the Wave Propagation Velocity in Granular Soils Using Discrete Element Method (DEM)
In the present paper, discrete element method (DEM) is used to study wave propagation phenomenon in granular soils. The effect of factors such as coefficient of friction, frequency, normal stiffness and soil gradation on the wave velocity is studied. Using the wall motion based on the sinusoidal function is the method of loading used in this simulation, through which the pressure wave is transf...
