Effect of oblique incident wave perturbation on rock spalling: An insight from DEM modelling
In order to study spalling failure characteristics of rock under oblique incidence of stress wave, a split Hopkinson pressure bar (SHPB) spalling test with a special shaped striker was simulated by Particle Fl...

Zonal disintegration phenomenon based on triaxial dynamic load test of hollow cylindrical sandstone specimens
In the process of deep roadway excavation, the zonal disintegration phenomenon of surrounding rocks has attracted a lot of attention from rock mechanics. There are relatively few studies on zonal disintegratio...

Rockburst prediction in hard rock mines develo** bagging and boosting tree-based ensemble techniques
Rockburst prediction is of vital significance to the design and construction of underground hard rock mines. A rockburst database consisting of 102 case histories, i.e., 1998–2011 period data from 14 hard rock...

Dynamic response and failure of rock in initial gradient stress field under stress wave loading
Once an opening is created in deep underground, the stresses surrounding the opening will be redistributed, inducing a gradient stress field. To understand how the ground rock in such a gradient stress field r...

Damage constitutive model of different age concretes under impact load
In order to investigate the mechanical properties and stress-strain curves of concrete at different ages under impact load, the impact compression tests of concrete at age of 1, 3, 7, 14 and 28 d were conducte...
