Drucker Prager plasticity model for ceramics

Hi everybody,

I am a phD student modelling the behaviour of the ceramics under nanoindentation using ABAQUS. I have read that Drucker Prager plasticity model is suitable for ceramics under indentation. To obtain these parameters ABAQUS users manual suggest doing a triaxial test, but I can not find any information relating triaxial test with ceramics (I only find it for soils and rock). Does anybody know another way  to obtain these parameters? Has anybody performed this test experimentally before?
