According to the actual scene, a simulation model of burglary resistant safety door subjcted to air non-contact explosions was established, and numerical simulation research on plastic deformation process of burglary resistant safety door under the loading of non-contact explosive air-blast wave carried. The results indicated that under the same loading of air non-contact explosive, plastic deformation process in burglary resistant safety door become longer, and the max plastic deformation was larger. The door would be partly damaged by air-blast wave and explosion production in condition of short distance between the door and the explosion point, and the whole plastic deformation would not be achived. A deformation quantity empirical formula of burglary resistant safety door subjcted to air non-contact explosions was obtained. The research could give some suggestions for the design of counter-terrorist door breaching explosive.
