Numerical investigation of initial conditions influence on the value of pressure impulse acting on special vehicle during acceptance testing

The article presents the results of works aiming at comparing a methodology of research on the effect of a pressure impulse coming from detonation of trinitrotoluene – TNT. Within the work, the influence of the explosive material detonation environment on the pressure impulse was studied. The analysis was carried out with Finite Element Method (FEM). Two cases of mine detonation in the sparse ground (sand) and explosive charge detonation in the tested model of a mine were selected. The model was described in the currently applied standardization regulations utilized for military and exploitation acceptance of special equipment.
