Numerical simulation of the effect of the near-ground explosion of energetic materials on the shell of a vertical incinerator

Abstract In order to study the effect of near-ground explosion energetic materials (EMs) on shell a vertical incinerator, different heights EMs 90 g TNT incinerator with exhaust gas outlet diameters was numerically simulated in three dimensions using AUTODYN software. The simulation results showed that maximum von Mises equivalent stress (mis. stress) occurred at upper edge outlet. Furthermore, mis. increased decrease height from center bottom and increase diameter incinerator. Importantly, existence constraint critical compared unconstrained open environment (157 mm). 80 mm 160 mm, 180 250 mm. design application incinerators, range can be reduced by reducing filling surface certain shock wave attenuation material.
