ANALYSIS OF THE EFFECT OF THE ALTITUDE OF THE DAMAGE EFFECT OF PLATES SUBJECTED TO EXPLOSION BLAST WAVE

摘要

Make establishment of the parameters of ideal gas model of different altitudes air.Using the linear numerical analysis software AUTODYN to calculate the blastoverpressure and impulse of different altitude environments. Make assessment ofdamage level of plate subjected to explosion blast by meaning of over-pressurecriteria. The results show that the altitude effect on the plate’s damage subjected toexplosion blast is significant and should not be ignored.
