Abstract
Physical properties of blast waves generated by detonation of hemispherical or spherical charge of TNT are well known. The aim of this chapter is to investigate the effects of small and medium sizes of high explosives. In this context, the studied explosives are TNT, C4 and composition B. The effects of small mass, geometry and nature of these explosives on the hydrostatic overpressure, arrival time and positive impulse are analysed. Fitted laws are given to calculate the overpressure and arrival time versus scaled distance expressed in terms of mass. The reverse laws are equally established. The results are compared with the abacus of UFC-3-340-2.
