Introduction The rock material deformation and failure can be divided into pre-peak and post peak two parts.
So rock materials mainly response a process that rock internal friction angle and cohesion continue ​​decreasing during the Strain-softening stage.

Introduction Cermet is a new type of engineering materials which has high strength, high hardness, wear resistance, good toughness and plasticity.
Fig. 4 RMS of Acoustic Emission and Table Speed As shown in Fig. 4, the AE RMS of two kinds of materials increases with the table speed increasing.
This is due to that acoustic emission energy materials released is in proportion to materials strain rate; the bigger materials strain rate is, the stronger acoustic emission signal [4].
