Abstract: For several decades, a blast wave profile due to explosive detonation has been investigated extensively. Base on a significant amount of experimental data, the blast wave propagation profile has been predicted at specific conditions. However, only center point of initiation for spherical shape explosive has been considered in most studies. The objective of this research is to investigate the effects of different point of initiation for military explosive (PE4) on the blast profile. In this experiment, a total 500 g of military explosive was initiated at three different initiation point which are top, bottom and also center of explosive. The explosive were detonated at a different distance from 0.5-4.0 m. The blast peak overpressure was captured using free field pencil probe and also high speed data acquisition system. The results shows that the top initiation produce the highest peak overpressure as compare with the center and also bottom initiation.
