A Three-Dimensional Numerical Investigation of Dynamic Fracture Characteristics of Rock Specimens with Preexisting Surface Flaws

Figure 10

Numerical simulation of the effect of three kinds of compressive stress waves on the failure process of specimens. The first row (a–d) is the maximum value of 50 MPa, the second row (a^′–d^′) is the maximum value of 60 MPa, and the third row (a^″–d^″) is the maximum value of 70 MPa.
