New question #685523 on Yade: https://answers.launchpad.net/yade/+question/685523
Hello, Regarding the CPM material model, would you please clarify the following: 1- From Yade documentation under the section: class yade.wrapper.Law2_ScGeom_CpmPhys_Cp : epsSoft(=-3e-3, approximates confinement -20MPa precisely, -100MPa a little over, -200 and -400 are OK (secant)) Strain at which softening in compression starts (non-negative to deactivate) what is the difference between epsSoft and epsCrackOnset (in Yade its described as: limit elastic strain)? is epsCrackOnset is the elastic strain limit in tension only, while epsSoft is the elastic strain limit in compression? 2- relKnSoft is defined in Yade documentation as "Relative rigidity of the softening branch in compression (0=perfect elastic-plastic, <0 softening, >0 hardening" Is relKnSoft a factor to reduce the elastic modulus of the bond in compression? 3- In the CpmMat, is the parameter "young" corresponds to the elastic modulus in both tension and compression? 4- Suppose I compressed two spheres into eachother, based on the CPM model, the stress-strain relationship is linear elastic at the begining, then what will happend to the curve? is there a strain limit after which the bond will be damaged?
