This command is used to construct an multi dimensional material object that has a Drucker-Prager yield criterium.
| nDmaterial DruckerPrager $matTag $a $b $c |
This Code has been Developed by: Peter Makenzie, U Washington and the great Pedro Arduino, U Washington
| $matTag | integer tag identifying material |
| $a | I don't know |
| $b | BUT |
| $c | I bet Peter and Pedro do! |
The material formulations for the Drucker-Prager object are "ThreeDimensional," "PlaneStrain," "Plane Stress," "AxiSymmetric".
THEORY:
The theory for Drucker-Prager can be found at wikipedia here
