Extended Drucker-Prager model in ANSYS GUI?
I have used classic Drucker-Prager material model in my 2D uniaxial powder compaction problem.
I have defined both linear elastic and inelastic (non-metal plasticity>drucker-prager) behaviors, but the simulation terminates due to a large number of warnings regarding the YIELD FUNCTION in Extended Drucker-Prager (EDP) model. See the warning message:
EDP plasticity: Yield Function Not Defined for element 909 and material 2.
I cannot find any option in Material Models Window to define yield function. There is not also EDP model there. Is it accessible only by scripts?
Where I have done wrong?
Any help is appreciated.
