Robert Caulk proposed the following answer:
Hello,

>>However the bonding parameters such as cohesion and tensile strength
are in the magnitude about 1e10 Pa which is too high if I want to get a
macro stress-strain curve and UCS with the unit or magnitude MPa like
the experimental tests.

Why do you presume that the micro-parameters should be of the same order
of magnitude as the macro-parameters?

Have you considered increasing the interaction range to simulate grain
interlocking better? [1]

Cheers,

Robert
