Hey,

I am simulating a number of gravels in a cylinder. And then make the cylinder to vibrate in a horizontal direction with frequency of 2~5 cps and amplitude of 10~25 mm. I am going to investigate compaction of the whole mass after vibration.

But the problem is that I don't know what value to put for damping to get realistic results?
I use linear elastic material for my particles.

Actually I found a range [1] for that, but I need to be more accurate.
Does anyone can help me?

Thank you in advance.
Regards,
Ehsan
