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

Slit tube responses and rock fracture characteristics in slit charge blasting under high in situ stress

Deep Underground Science and Engineering, EarlyView.
In this article, the finite element method‐smoothed particle hydrodynamics adaptive coupling algorithm is applied to numerically simulate and analyze the dynamic response of the slit tube and the crack propagation under high in situ stress. The dynamic response of the slit tube mainly exhibits radial response in the vertical direction of the slit and ...

Experimental and constitutive modeling investigations on marble in Jinping Underground Laboratory

Deep Underground Science and Engineering, EarlyView.
The objective of this study is to reveal the underlying mechanisms behind the brittle‐ductile transition of the marble through a combination of experimental research and constitutive modeling. A series of triaxial compression and triaxial cyclic loading tests are conducted.
