Analysis the Effect of Explosion Efficiency in the TNT Equivalent Blast Explosion Model

In this study, the analysis will focus firstly on the analysis of the effect of an increment of explosion yield, η value between 2 and 9 % and its correlation toward the parameter peak side-on overpressure po, the duration of the positive phase td compared to diagnostic features of explosion damage results translated according to criteria developed by V.J. Clancey. Secondly, the aim is to validate the recommended methods of yield factor by Less [1] with estimated results (η between 2 and 9 %) by using TNT model in comparison with the physical observation damage of VCE incident impact at Flixborough in 1974.
