This paper reports on a new methodology to provide rapid predictions of blast loading from spherical TNT charges. The rapid prediction method described has been coded by the authors into the open source Scilab and Matlab programming languages. The approach presented is based on experimental data and empirical formulae collected in official standard Unified Facility Criteria. The correctness of the results is proved for the explosion of spherical, condensed charges, both in free air space and as surface explosions. By taking a standard engineering approach, any engineer should be able to predict the primary features of explosive loading and take it into account during their design processes. This code is a part of the module called Sapper-Blast. Moreover, the main part of the paper also includes a comparison of the outcome with numerical verification. The results are presented for TNT spherical charges. The numerical consideration is performed using ABAQUS Explicit code. The results allow an informed assessment of the basic properties of an explosion for an equivalent mass of TNT for any kind of condensed, spherical charge. In addition, the approach presented demonstrates the overestimation of official results due to numerical approaches.
