Hi everyone,
I am currently working on the modeling of the railroad track. In my model, I have simulated the rail and the crossties by beam elements and used connectors to add longitudinal elastic and friction elements. The rail is pushed by a concentrated force in axial direction.
I am seeking to see the different slip interfaces by changing the loading rate. Therefore, I have used dynamic analysis and added lumped masses. Right now, the slip is only occurring at the interface with lowest friction resistance (tie-ballast interface).
Any idea how I can change the slip interface disregarding the friction resistance and make it only dependent on loading rate (simulation time duration)?
There are some figures below to clarify.
Thank you.
