Hello,
i have a general question regarding the usability of experimental measurements for DEM Simulations.
I have tested materials in a ring shear tester. The ring shear tester gave me results for static friction angle, dynamic friction angle and cohesion.
Can i make an argument for direct usage of these parameters in my DEM simulations? Or are these values useless in the DEM realm?
A colleague says they're bascially useless since the DEM models are not using the same physics as the experiments. I would agree to the point that a ring shear tester is testing for the bulk values of static friction etc. and in DEM we're using particle values for the same parameters.
So are the experimental values useless?

Great Starting Points
Hello,
Experimental results are great to use as a starting point to calibrate your model.
It is correct to say that you will seldom use the laboratory measured value.
