But the response that I get is purely elastic and no hardening is observed in the output even if I vary kinf and ko by any amount. Please help .. Thanks wipe model BasicBuilder -ndm 3 -ndf 3 #--create the nodes node 1 1.0 0.0 ...

Re: Druker Prager material to simulate triaxial test

Thank you for your suggestion.. I tried it , but it still doesnt work!! The manual says that the updateMaterial command is for PressureDependMultiYield . Should it also work for Druker Prager material?? Thanks
