Re: [Question #707253]: Biaxial test with rolling friction
Question #707253 on Yade changed:
https://answers.launchpad.net/yade/+question/707253
Yipeng Xie posted a new comment:
Adding to the previous comment, I ran two sets of comparison tests. I
monitored the i.phys.moment_bending and the i.phys.normalForce at the
end of compaction and the end of shearing, and I found that the contacts
information is the same for both tests at the end of compaction, but
quite different at the end of shearing. From the output results, both
tests activate the rolling-resistance moment before the shearing and
assign the correct phys.maxRollPl to every existing and potential
contact. So I'm wondering what is the reason for the difference?
(Both for packing composed of 50 particles with radius = 0.1 and
CohesiveMat)
