Blast Effects Evaluation Using TNT Equivalent
Zoran Bajić Jovica Bogdanov Radun Jeremić
This paper shows blast parameters of high explosives commonly used in explosive ordnance of Serbian armed forces regarding TNT equivalents. Primary blast wave parameters, overpressure, impulse and positive phase duration are calculated using modified Sadovskiy equations and the modified K-B equation. TNT equivalents of the observed explosives are determined using thermochemical calculations based on BKW EOS parameters. The calculated blast wave parameters show significant influence of used explosives concerning the TNT equivalent. Key words: explosive materials, physics of explosion, blast wave, blast wave effect, thermochemical calculation, TNT equivalent, equation of state, Sadovskiy equations.
