Experimental and numerical investigationon heavy-caliber shaped-charge penetration in thick concrete target
2016
The independent developed software EXPLOSION-2D was adopted to
simulate the heavy-caliber shaped-charge forming, and the laws of
heavy-caliber shaped-charge forming were obtained and the influence
of blasting height for shaped charge penetration thickness concrete
target was simulated. Based on the performance parameters of the penetrators,
two kinds of shaped-charge structures which had good penetration effect
were selected to penetrate in the thick concrete target. According
to the simulation results the best shaped-charge structure which could
penetrate the thick concrete target well was designed and the corresponding
experiments were carried out. The concrete target after the experiment
was cut to evaluate the concrete target damage in different location
by the inside damage of concrete target and the hole diameters of
different location were measured. The test conditions were simulated
by the EXPLOSION-2D software and the simulation results was compared
with the experimental results. The comparison results show that the
numerical simulation technology can evaluate the damage of concrete
target effectively.
