Karol Brzezinski proposed the following answer:
Hi Guo,

Yade is really well-documented. I recommend reading the Guided Tour, DEM
Formulation, and User's Manual. There is a section about clumps as well
[1].

You can find there that "In Yade (class Clump), clump members behave as
stand-alone particles during simulation for purposes of collision
detection and contact resolution, except that they have no contacts
created among themselves within one clump. "

Hence, there are no interactions between the clump members. Clump
members' arrangement is rigid.

Cheers,
Karol
