Rock Dynamic Fracture Characteristics by Mini-Linear Shaped Charge Jet Penetration: A Case Study

Table 2

Material parameters of copper in the model.

ρm (g/cm^3)	(GPa)	A (MPa)	B (MPa)	n	C	m	EPS0
8.96	46	900	290	0.31	0.025	1.09	0.1 × 10^−5
PC	SPALL	IT	D1	D2	D3	D4	D5

Note: ρ_m is the density; A, B, and C are the constants of the material and can be determined by torsion tests under different strain rates.
