The geotechnics of hard soils - soft rocks. Proceedings of the second international symopsium on hard soils-soft rocks, Naples, October 1998. (Two volumes).   737-744
It is well known that soft rocks exhibit strain-hardening and strain-softening during the shearing process. Under the confining pressure near the consolidation yield stress, it has been reported that soft rocks exhibit both strain softening and ne...
