[Yade-users] [Question #694240]: How to reach ctitical state in a triaxial compression test?
New question #694240 on Yade: https://answers.launchpad.net/yade/+question/694240 Hi everyone, I'd like to ask you the help on any possible suggestions to make a sand sample reach the critical state (no volumetric strain occurs) in triaxial compression test. I use cohFrictMat (with rolling resistance) and CohesionMoment for the simulation, the boundary condition is six rigid walls. And I have been testing a lot on calibrating the parameters of my model, but I still can't get a result which can reach the critical state, even at larger strain level, as a typical result of my tests in [1]. Refer to papers such as [2] and [3], it is very nice that the critical state has been captured. I guess I miss some knowledge on capturing this behaviour. I feel that the occurrence of critical state could be affected by many factors (not sure). I'd like to ask your valuable suggestions on this issue. For example, does the occurrence of this state only depend on the contact parameters? Is it related to the strain rate? Any efficient way to get this state? Thanks very much!

Question #694217 on Yade changed: https://answers.launchpad.net/yade/+question/694217 Status: Open => Answered Jan Stránský proposed the following answer: > Does it mean that the whole material is made of the same material? this is one (bot not the only one) approach > what material model and the physical module would be better satisfied? "something between" probably. Concerning modulus, the best value is such that your overall/macroscopic modulus match the experiment/expectation. Concerning strength, it is a bit more tricky. But similarly, some macroscopic response (strength, failure mode etc.) should match experiment/expectation. cheers Jan -- 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 #694208]: particle blow up
Question #694208 on Yade changed: https://answers.launchpad.net/yade/+question/694208 Status: Open => Answered Jan Stránský proposed the following answer: > how can we get the real penetration resistance when the penetrator penetrates into the sample? using PFacets > As for the PFacets, does this will solve the sphere-edges/sphere-vertices > contact problem? > or what is the effect of using PFacets? can you explain more about this? The main purpose of PFacets (IMO) is to improve this facet behavior. PFacets consist of vertex/node - edge - facet hierarchy. If the contact od of sphere-vertex type, the interaction is considered with this one vertex, not any more with more vertices or edges of facets. If the contact is of sphere-edge type, the interaction is considered with this one edge, not any more with more facets. Finally the sphere-face type of contact is handled naturally. So for this problem, pfacets are worth to try at least. cheers Jan -- 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
