Chien-Cheng Hung gave more information on the question:
Hi Jan,

Sorry, let me make it clear.

As far as I know, the friction angle we assign or modify in [1] and [2] stands for the internal friction angle of the material.
In the meanwhile, these two parameters also represent the interparticle friction angle that describes the contact friction between particles.

I happened to see Luc's comment in [3] saying not to mix up the internal
friction angle of material and the interparticle friction angle which I
think are the same thing based on my understanding.

So I would like to ask whether the values in [1] and [2] can also be
considered as the interparticle friction coefficient?

Cheers,
Chien-Cheng
