Özet
There are some equations to establish the relationship between blastwave parameters with scaled distance. In this paper, the resulting data from numerical simulations by AUTODYN-1D for different marked distances from detonation points and different amounts of charge are compared with results from experimental data and equations. To sum up, some equations for evaluating blastwave parameters are presented, which are in excellent conformity with numerical and experimental data. In addition, the importance of the effect of altitude from sea level is clearly expressed and the presented equations are modified by proposing a modifying coefficient.
