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

Influence of the continuously increasing normal stress to the failure in case of shearing test [PDF]
, 2002 In a conventional shearing test the normal force or the normal stiffness is kept constant during the experiment. Sliding under constant normal load occurs in slopes if the environment is not changing during the process. The goal of this paper is to

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.

Deep Underground Science and Engineering, EarlyView.The permeability variation of rocks during complete stress–strain processes was investigated. A mathematical model describing the influence of rock damage on permeability was constructed. The permeability–stress relationship between soft rock and hard rock was proposed.

Determination of hypoplastic parameters for a typical gravel backfill material of railway bridges [PDF]
E3S Web of ConferencesLaboratory test programs on gravel are rare due to the maximum grain size of the material. In this paper an experimental program with triaxial tests under cyclic loading and oedometric tests on highly compacted gravel specimens, representative for bridge

A finite-strain hyperviscoplastic model and undrained triaxial tests of peat
, 2017 This paper presents a finite-strain hyperviscoplastic constitutive model within a thermodynamically consistent framework for peat which was categorised as a material with both rate-dependent and thermodynamic equilibrium hysteresis based on the data ...
