Forecast and Simulation of Peak Overpressure of TNT Explosion Shock Wave in the Air

Pengfei Cheng

Open publisher page 10 citations

Abstract

Differences between several scholars′ forecasts of peak overpressure have been compared by the con-trastive analysis of research on TNT explosion shock wave spreading in the air.A new formula has been summed up,and LS-DYNA has been used to simulate the spreading of shock wave in the air generated by TNT explosion on different conditions.The numerical values are less than empirical formula′s.The results of the explosion with heavier load are more approximate than the forecasting results of empirical formula.So it′s necessary to do more research on explosion shock wave parameters.
