Experimental study on impact dynamics and failure characteristics of coal specimen under true triaxial conditions

Experimental study on impact dynamics and failure characteristics of coal specimen under true triaxial conditions

Deep coal is mostly in a three-dimensional unequal stress state. In order to study the dynamic characteristics of coal under impact load, the dynamic failure mechanics experiment of coal was carried out by true triaxial Hopkinson experimental system. This system can be used to provide uniaxial (σ1≥σ...
