Abstract

The pre-buried method has the potential to measure the Depth of Penetration (DOP) of a projectile into a target with a large dimension and potential dangers. Based on the numerical simulation of a reduced-scale projectile into unreinforced concrete target, the mechanism of the accelerometer pre-buried method is studied. The reasonable pre-buried location of the accelerometer is determined, the relationship between the target acceleration and the DOP of the projectile is constructed and the precision of the accelerometer pre-buried method is also discussed. Finally, the source of the maximum of target acceleration, i.e. the maximum radial expansion, is investigated. Keywords: mechanics of explosion, accelerometer pre-buried method, target acceleration, DOP of projectile, unreinforced concrete target.
