Experimental investigation of damage evolution during strain burst in brittle rocks for deep mines
… damage, high confining pressure and various loading rate on the overall mechanical behaviour of highly brittle granitic rocks leading to strain burst. Strain burst is related to the elastic stored strain energy and how this stored energy is released during the unstable spontaneous failure. …

Scale-model investigation of brittle tunnel failure using a true-triaxial device
… a series of tunnel model tests using a true-triaxial cell, a mock miniature tunnel boring machine (TBM), and acoustic emission (AE) monitoring, and (3) proposing more robust analytical methods and predictive models for brittle failures. The analog rock was designed to mimic the brittle …

Borehole Breakouts in Transversely Isotropic Posidonia Shale
… due to the higher burial depth. Conventional triaxial borehole breakout experiments on specimens with different borehole diameters showed that, when the diameter of the borehole is increased, the stress required to initiate borehole breakout decreases to a constant value. This value can be …
