When I change the material for some existing bodies using the following code, the simulation cannot go through. It note that 'python argument types in None.None(Body, function)'. There is an error with the b.material= newMat. Could you please tell me how can I deal with it? for b in bodiesToBeUpdated: b.material = newMat Best regards, Benxin -- 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

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

Question #699346 on Yade changed: https://answers.launchpad.net/yade/+question/699346 Wang Benxin posted a new comment: Hi Robert, Thank you for your interest in my question. >>I don't quite understand. What is "stable after the yield stage". Do you mean the material should be perfectly plastic? I guess yes, because you say "no strain softening." Yes, you are right. The material is perfectly plastic. Its property is like the Fig.9 in the literature https://link.springer.com/content/pdf/10.1007/s10409-015-0524-4.pdf >>What is "big plastic characteristic?" Can you describe that a bit more technically? "big", "small" what does it mean? are those relative values to some other behavior? "big", "small" are use to describe the behavior of the material like 'perfectly' you said. >>What is "PLA?" 'PLA' is the polylactic acid. https://sv.wikipedia.org/wiki/Polylaktid Cheers, Benxin -- 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
[Yade-users] [Question #699346]: How to simulate the material with big elastoplastic property such as PLA
New question #699346 on Yade: https://answers.launchpad.net/yade/+question/699346 I am simulating the material with big elastoplastic property. The stress-strain curve of the material has the normal elastic characteristic, but it will tend to be stable after the yield stage showing that it has a big plastic characteristic and there is not a strain softening stage. The material is just like PLA. My question is what material and constitutive law are supposed to be used properly. Is there any example for it? -- 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
[Yade-users] [Question #699345]: How to calibrate the magnitude of local stress field in 2D specimen
New question #699345 on Yade: https://answers.launchpad.net/yade/+question/699345 I am simulating the uniaxial compression of rock specimen in 2D using spheres. 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. The local stress field is also in the magnitude 1e10 Pa for the solving result. But the magnitude of stress field in the experimental uniaxial compression is 1e6 Pa. Hence, my question is that how o calibrate the local stress magnitude as the experiment in the numerical model. -- 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
[Yade-users] [Question #698072]: How to import the parking file and change contact paramters before the specimen is compressed
New question #698072 on Yade: https://answers.launchpad.net/yade/+question/698072 Hellow everyone, I am in the stage of calibrating the macr-mesos mechanical parameters. Because the specimen packing takes long time, I want to do the calitration by importing the packing file and modify the contact parameters before the specimen is compressed. The questions are as follows: 1) What's the script data structure? 2) Is there any example which can be used to refer to? Many thanks for your any respond.
