Dynamic notched semi-circle bend (NSCB) method for measuring fracture properties of rocks: Fundamentals and applications

Journal of Rock Mechanics and Geotechnical Engineering, 2019
Rocks are increasingly used in extreme environments characterised by high loading rates and high confining pressures. Thus the fracture properties of rocks under dynamic loading and confinements are critical in various rock mechanics and rock engineering

Experimental study on dynamic behavior analysis of coal and its acoustic emission response characteristics under impact failure

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 96-105, March 2026.
Based on acoustic emission response characteristics, it can be more accurate to identify the damage evolution process of coal under the combined dynamic and static loads, reveal the moment corresponding to coal damage, and identify the characteristics of coal failure. The research results are conducive to the further use of acoustic emission monitoring

Stress analysis of crack characteristic of anthracite under dynamic loading

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 56-65, March 2026.
In this article, the dynamic compression test of anthracite under five strain rates is carried out, the evolution law of three kinds of crack characteristic stress is analyzed, and a prediction model of the crack characteristic stress threshold considering the strain rate effect is established. Then, the rationality of crack characteristic stress under
