Ultra-high g deceleration–time measurement for the penetration into steel target

This paper presented an ultra-high g deceleration measurement device for studies of the penetration into steel target. More than 145,000g deceleration value was measured by this device during a penetration experiment where the steel target was 50 mm thick. Both the design of the device and the experiment of penetration into steel target were described in detail. Numerical simulation utilizing ANSYS/LS_DYNA was carried out with the same penetration condition. The numerical simulation analysis results were consistent with the experimental result. However, compared with theoretical analysis result of a previously published penetration model, the experiment one showed some disparities.
