Question #251712 on Yade changed: https://answers.launchpad.net/yade/+question/251712
Hongyang Alex Cheng posted a new comment: Thanks, Anton Due to my limited knowledge I haven't seen any formulation for contact stress like in [1], but I'll check it. If I am not mistaken, [1] returns normal stress and tangential stress at particle contact level. I've been thinking whether it's better to export mean stress p and deviatoric stress q for post-processing instead of normStress and shearStress. That's why I raised my second question. Here is the nonlinear equations I wanna solve where si (i=1,2,3) are principal stresses, I1, I2 and I3 are three stress invariants. s1+s2+s3 = I1 s1*s2+s2*s3+s3*s1=I2 s1*s2*s3=I3 [1] https://github.com/yade/trunk/blob/master/pkg/dem/Shop_02.cpp#L176 -- You received this question notification because you are a member of yade-users, which is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
