Re: [Yade-users] [Question #699345]: How to calibrate the magnitude of local stress field in 2D specimen
Question #699345 on Yade changed: https://answers.launchpad.net/yade/+question/699345 Wang Benxin posted a new comment: Hi Robert, In experiment the stress field was calculated base on the damage evolution constitutive equation. And it's magnitude is 1e6 Pa. The numerical test uses the Law2_ScGeom_JCFpmPhys_JointedCohesiveFrictionalPM. And the local stress in numerical model is exported by VTK and showed in ParaView. -- You received this question notification because your team yade-users 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

I got the local stress field in experiment. Hence, I want to make the comparison and verification of local stress field between simulation and experiment. >>Have you considered increasing the interaction range to simulate grain interlocking better? [1] Yes, I had increased the interaction range as the paper saying.

Question #699345 on Yade changed: https://answers.launchpad.net/yade/+question/699345 Status: Open => Answered Robert Caulk proposed the following answer: Hello, >>However the bonding parameters such as cohesion and tensile strength are in the magnitude about 1e10 Pa which is too high if I want to get a macro stress-strain curve and UCS with the unit or magnitude MPa like the experimental tests. Why do you presume that the micro-parameters should be of the same order of magnitude as the macro-parameters? Have you considered increasing the interaction range to simulate grain interlocking better?
