A version of the Drucker-Prager subroutine without the cap can be found here:
https://data.mendeley.com/datasets/5ccwt5fv7y/8
However, there are some discrepancies compared to the standard Abaqus Drucker-Prager model, particularly in capturing certain material behaviors. You will likely need to develop this subroutine yourself, as researchers often retain such routines for their own use.
