Theoretical Calculation and Experimental Analysis on Initial Shock Pressure of Borehole Wall under Axial Decoupled Charge

Table 6

Material model and state equation parameters of the air.

Density (kg/m^3)	C0	C1	C2	C3	C4	C5	C6	E0 (GPa)
1.29×10^−2	0	0	0	0	0.4	0.4	0	0	1.0

Note: C₀ ~ C₆ are multinomial coefficients of the state equation; E₀ is initial internal energy per unit volume of explosive; is relative volume.
