Extended Drucker-Prager model in ANSYS GUI?

amiratrian

Dear all,

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.    

Thanks,

Amir
