Repo is for incremental driver that is integrated with a strain softening Mohr-Coulomb model. The repo was originally written by A. Yerro-Colom (use Yerro (2015) for reference).
Information about the constitutive relation:
- Uses a smoothed MC yield surface as presented by Abbo and Sloan to alleviate undefined derivates at the kinks
- Has both an Oritiz-Simo integration scheme and an Euler/Newton-Raphson integration scheme
