Hi to all
I would like to use DEM to simulate the pushing of a granular soil due to a compressive
force from one of it's sides.
This subject is Geotechnics is called the stick-slip phenomenon. We have done the experiments on a box
filled with beads to simulate the granular soil. The box is open from the top but one of it's sides is a moving
wall that can be pushed towards the granular medium with a constant compressive force. Progressively in time
a line somewhere in the middle will develop to show where the soil will break.
I would like to ask all users if this can be simulated with the available software.
Don't worry about using the beads. Replacing these with little balls of 4-5 millimetres in diameter will be ok too.
Advice from all of you on how this can be done will be very helpful
Many Thanks.

Hi,
Hi,
I think the 'fix mesh/surface/stress/servo' would be a way to do this. It controls the wall to reach a certain force. For the controller I would use a PID controller, but if there is too much disturbance try a PD controller.
Regards.
