The Research on Penetration of New Annular MEFP

According to the detonation wave collision theory, initiation from two ends of charge, the liner will close to the middle to form high velocity MEFP. The software Autodyn to be used to study the penetration capacity of a single Annular MEFP was studied. With increase of axis curvature radius, the ratio of length of width is decrease, the penetration capacity declined. It is partitioned hole into two parts which is formed gourd-shaped in the typical penetration. For equal liner and unequal liner, although the velocity of unequal liner is higher, the penetration capacity is weaker.
