Dynamic fracture and energy consumption characteristics of coal-series sandstone after heat treatment

Dynamic fracture and energy consumption characteristics of coal-series sandstone after heat treatment

In this paper, the dynamic loading tests of sandstone after heat treatment at 25-800°C are carried out by using the split Hopkinson pressure bar test system. Combined with the theory of energy dissipation, the dynamic fracture and energy consumption characteristics of coal-series sandstone are syste...
