[Yade-users] [Question #683775]: modelling "solid bridges" between particles
New question #683775 on Yade: https://answers.launchpad.net/yade/+question/683775 Hello, I would like to model solid bridges between particles of a packing as beams linking the particles together. The beam model would be defined by a young modulus, a shear modulus, cross section and length. The solid bridges at particle scale could brake when a certain stress exceeds the tensile strength of the material. Is it possible to model this kind of solid bridge between particles with Yade ?? Couln't find any informations about that. Thank you very much for informations, Best wishes, Fr. -- 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 #683775 on Yade changed: https://answers.launchpad.net/yade/+question/683775 Status: Open => Answered A Dinesh proposed the following answer: Hi Rioual, Yes you can model such kind of physics in Yade. To model such phenomena, we have to create bonds between particles, which follow certain physics. These bonds are created to act like a cohesion force between the particles of the solid bridge. And these bond will have a tension and shear stresses. There are examples in yade which model this. See for example [1]. To understand the physics behind it, please look at [2], which describes the physics as well as the implementation of the model in yade.

Question #683775 on Yade changed: https://answers.launchpad.net/yade/+question/683775 Status: Open => Needs information Jan Stránský requested more information: In the described approach, the "cylinder" is the interaction, the connection between spheres (as being interaction, it does not create interactions with other "cylinders" or spheres) It is also possible to use physical cylinders able of further interactions, but I do not have personal experience with them. So please be more specific on haw you define "solid bridges between particles" :-) 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
