Abstract
According to actual conditions, a simulation model of a burglary-resistant door subjected to non-contact explosions was established, and the plastic deformation process and law of the door under loading of non-contact explosion and air-blast wave were studied. The results indicated that under the same loading of non-contact explosion, the plastic deformation response of the burglary-resistant door under rotary boundary conditions becomes longer than that of the door with four edges clamped; and the maximum plastic deformation is much larger than that of the door with four edges clamped; the door is partly damaged due to air-blast wave and explosion products in case of the shorter distance between the door and the explosion center, and the plastic deformation of the whole door can not appear; a deformation computation empirical formula for the burglary-resistant door subjected to non-contact explosions is obtained. The study provided a guidance for explosive design to break a door for the purpose of anti-terrorist.
