Sažetak
Numerical modeling of detonation by the Wood- Kirkwood detonation theory requires the detonation front curvature radius to be specified as an input parameter. In this work we present two empirical equations for the estimation of the curvature radii of various explosives. The equations are derived based on a large number of literature-reported experimental data on the detonation front curvature radii as a function of charge radii and failure radii. The proposed equations predict the front curvature radii with the root mean square error of about 30%, which is a significant improvement compared to previously proposed empirical equations.
