Numerical implementation of the Hoek-Brown material model
with strain hardening

ABSTRACT: A numerical implementation of the Hoek-Brown criterion is presented, which handles strain
hardening behavior. The parameters involved in the Hoek-Brown criterion depend on the accumulated plastic
strains based on an arbitrary set of user defined points. The implementation is based on return mapping ...
