Stress analysis of crack characteristic of anthracite under dynamic loading
Deep Underground Science and Engineering, EarlyView.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
