In hole velocity of detonation (VOD) measurements as a

For this, low density and low VOD explosives such as ANFO are more efficient than high strain energy explosives as the extension of radial cracks are terminated at joints , . Detonation velocity of the explosive can be used to calculate the impedance of an explosive which is defined as the product of the density and the detonation velocity of the explosive.
