I believe I've resolved the issue. The problem was with the value of "intRadius." I'm not entirely sure what it represents, but I increased it to 1.5, and now the model is functioning correctly. Previously, when it was set to 1.3, the model was only controlled by tensile strength. However, increasing the cohesion had no observable effect. Do you know what is "intRadius"?

Question #707758 on Yade changed: https://answers.launchpad.net/yade/+question/707758 Yade Guide posted a new comment: Hey mahdi2023, check out some related threads. This is an automated reply. Title: "A problem with 'JCFmpMat'" Question by qfxx-123 on 19 Jun 2023: The user is seeking clarification on the differences between 'JCFpmMat' and 'FrictMat' when their tensile strength and cohesion are set to zero. Despite having similar structures, the results of the two triaxial tests were significantly different. The user wants to know why the sample is stress-free at the first iteration of a JCFPM simulation, the use of 'intR>1' in the engine when particles are touching each other, and how to edit the code if they want the results of 'JCFpmMat' to be same with 'FrictMat'. The user has set 'intR' to 0 and tried again, finding that the strength of the two methods is identical. They thanked the person for their guidance. https://answers.launchpad.net/yade/+question/707022 Title: "JCFpmMat parameters define" Question by voyagening on 29 Nov 2020: The JCFpm parameters in YADE are used for simulating jointed materials like fractured rocks. These include 'cohesion' and 'jointCohesion', which account for different mechanical properties of the matrix and fractures, respectively. Additional parameters such as 'jointDilation' and 'jointSurface' allow for defining the dilation of jointed contacts following the physics of rock joints. Aaron expressed gratitude for a helpful explanation and plans to further research these concepts. https://answers.launchpad.net/yade/+question/694253 Title: "How to set the parameters of JCFpmMat?" Question by qfxx-123 on 11 Jul 2023: The user is seeking clarification on how to set parameters in JCFpmMat, specifically tensileStrength and cohesion in relation to degree of interlocking. Luc provides guidance by suggesting defining the C/T ratio of BPM equal to compressive strength / tensile strength of the rock being modeled. https://answers.launchpad.net/yade/+question/707257 -- 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

When you assign tensile strength, the tensile strength plays a role. When you set the tensile strength to 0, it does not play a role. So far everything makes sense. Can you elaborate?

Question by suncan on 30 Oct 2021: The user is having trouble with a simulation and needs help setting normal stiffness. They provided code attempting to append a new material (WallMat) with jointNormalStiffness=2.5e6 and jointShearStiffness=1e6, but the simulation isn't working as expected. Karol suggests consulting the FrictMat documentation and using young and poisson properties like in the case of spheres. https://answers.launchpad.net/yade/+question/699278 Title: "Boundary properties" Question by johnav on 13 Nov 2019: The user is seeking guidance on properties for plates created with facetbox in YADE to perform strength tests on 'rock' samples. They want to know the appropriate properties to assign and whether the plates should be made rigid like in a real test apparatus. The continuation provides information about setting up the simulation with YADE, suggesting that bodies created with facetBox() have zero mass and inertia by default. https://answers.launchpad.net/yade/+question/685848 Title: "damping in ViscElMat" Question by feda.s on 28 Nov 2016: Jérôme Duriez's solution resolved Jim's question about simulating gravity. In response to suggestions and comments, it was noted that using global damping instead of viscous damping may be a better approach for reaching the target porosity in the specific case. https://answers.launchpad.net/yade/+question/404455 Title: "Evolving material properties and timestep instability" Question by rborela on 19 Aug 2015: The user is experiencing numerical instability in a dense pack simulation with a porosity of 11%. Despite gentle stiffening and shrinking, the time step is decreasing rapidly, resulting in 'nan' values or particle explosion. The user seeks suggestions to handle this issue. Thanks Jan Stránský, that solved my question. Thank you very much, Jan. I changed that and ran the simulation from beginning to end and it worked perfectly :) https://answers.launchpad.net/yade/+question/270524 -- 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
