Energy characteristics in quasi-static fracture of granite samples were quantitatively studied, and a new strain burst vulnerability criterion based on energy-release rate for brittle rocks was proposed. The results revealed that the quasi-static fracture toughness and energy-release rate are highly ...

The dynamic constitutive equation of coal rock dynamics is derived based on the stress–strain curve and stress–strain curve of coal rock dynamics under dynamic load environment. The dynamic constitutive equation is then dimensionless processed, and the similarity criterion is introduced to derive the...
In this study, the brittleness indexes calculated based on the energy analysis in the stress-strain curve can be used to accurately evaluate the sensitivity of the brittleness to the confining pressure and the anisotropy of the rock materials. Moreover, these methods can greatly reveal the physical...

Furthermore, a method to calculate rock energy was proposed based on the area of the loading and unloading curve. The experimental results show that the greater the surrounding rock pressure is, the smaller increase rate of lateral and volumetric strain in the postpeak stage will be when the ...
Three stages are identified based on the evolution of AE energy to analyse the coal burst process. The first significant increase in AE energy is an indicator for the beginning of the late incubation stage of coal burst. A comprehensive classification criterion for coal burst prediction is proposed...
High in-situ stress and rock burst have been important issues for risk assessment of deep tunnelling. The issue of prediction and control of rock burst remains to be solved, though various researches have been done. Based on the Lhasa-Li... J Wang,Y Xue,Y Guo - 《Iop Conference》 被引...
