| Abstract: | It was about 20 years ago that the damage mechanics was presented into rock mechanics research.In recent years,there were so much research being reported.Some representative research was summarized in this paper.Some definitions were presented emphatically,which is of damage parameters in macro continuum mechanics.Several damage evolvement models were reviewed in this paper.Contemporarily,the macro|damage and micro|damage study were described.The combined method between the macro and micro research formed the so called modern failure mechanics whic was considered to be the promising direction in the future studies of brittle rock materials. |
