Hi there,

I want to learn more about the "Modified Drucker-Prager/Cap model" empolyed by Abaqus (https://help.3ds.com/2018/english/dssimulia_established/simacaematrefmap/simamat-c-capplastic.htm?contextscope=all).  Such as, the basis of the modification to the original Drucker-Prager model, the meaning of the new introduced parameters and how to calibrate them.

Where does this model come from? Is there a published peer-reviewed paper, or something like that, for "Modified Drucker-Prager/Cap model"? I couldn't find one on the website of related documentation.

Thank you so much~~

Best
