Abstract: In this paper, AUTODYN is used to establish a numerical simulation model of four commonly used explosive materials, such as 2.0 kg sphere bare charge TNT, H6, AL/AP-HE and PBX9010. The explosion shock wave and thermal damage effect is simulated, and the peak value of shock wave overpressure and explosion fields temperature are compared and analyzed. The analysis results show that the damage effects produced by different explosive materials are very different. Under the same charge quality, sequence of shock wave overpressure peaks of four explosive materials is PBX9010＞H6＞TNT＞AL/AP-HE, while that of temperature peaks of four explosive materials is AL/AP-HE＞PBX9010＞H6＞TNT. Within a certain range from the explosion center, the explosion temperature field can maintain high temperature for a long time, and its temperature decay rate is much smaller than that of the shock wave. Therefore, the temperature has longer damage time and better damage effect.
