Question #690521 on Yade changed: https://answers.launchpad.net/yade/+question/690521
Description changed to: Dear all, I'm trying to obtain an exponential softening shear behavior (damage-plasticity) after peak stress instead of Mohr-coulomb failure with cohesion which is currently implemented CPM model in Yade. shear stress will be calculated as follows, sigma_S= k_s*(1-D)*(Us-Us_Pl) where D is scalar damage variable and sigma_S,Us, Us_Pl are vectors D=1- exp(-|Us_pl|/constant); where , |*| : maginitude and yield criteria is F=|sigma_S|- Cohesion*(1-D) , cohesion is scalar value say ,1e6 like that from yield function F, I can calculate the scalar value of plastic shear displacement, but the problem is how to update the plastic shear displacement vector? Could you please help me to solve this issue? -- 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
