Brittleness evaluation method based on pre-peak crack initiation and post-peak characteristics of rock

The existing researches show that the brittleness of rock is closely related to the initiation and propagation of internal microcracks, but there are few brittleness evaluation indexes considering the characteristics of rock initiation. Based on the theoretical analysis of brittleness and the charac...
