Behandlung des Schotters als Vielkörpersystem mit wechselnden Bindungen

By means of molecular dynamic simulation, each individual ballast stone in the ballast track can be simulated in the model.  It is investigated to what extent it is possible to define contact force laws, material parameters and geometry variables in such a way that the resulting computational model reproduces the essential behaviour of the real system. Furthermore, possible areas of application of molecular dynamic simulation are mentioned.
