How to determine the interaction parameters between different bulk materials?

Hi Support,

Assuming that I have two bulk materials A and B, and I would like to calibrate the interparticle interactions, including A-A, A-B and B-B. Take the static angle of repose test as an example, could I calibrate A-B interactions by performing the test with mixture of A and B (on the premise that the A-A and B-B interaction parameters have been calibrated)?

Regards,
