New question #210907 on Yade: https://answers.launchpad.net/yade/+question/210907
In real triaxial compression of granular sand, relative density is usually a key parameter to control the initial state of the sample. I want to simulate the triaxial compression using yade. topic here is all about the sample generation. I use radius-expansion method with different inter-particle friction angle to generate loose or dense sample, friction angle 0 results the densest sample, and friction of maxmimum equals to that used later in deviatoric loading results loosest one as proposed by Chareyre etc. I want to relate the relative density with friction angle, finally I do that. I calibrate parameters using a contact model considering rolling resistance, but if fails for the rolling resistance. So I guess that the problem is wrong, how to relate my numerical sample with real granular soil using the radius-expansion method? and anybody has advanced method to generate numerical sample to model real granular sand? thanks -- 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 : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
