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

Table 1

Three flaw dip depths, model case, loading case, and homogeneity indices of rock are considered.

Case number	Cutting depth of flaw (mm)	Homogeneity index	Model case	Loading case
1	6	m = 4	Model I	Loading caseI
2	6	m = 4	Model I	Loading caseII
3	6	m = 4	Model I	Loading caseIII
4	6	m = 4	Model II	Loading caseI
5	6	m = 4	Model III	Loading caseI
6	20	m = 4	Model I	Loading caseI
7	40	m = 4	Model I	Loading caseI
