    Abstract
  • To study similar law of the fragmentation effect of penetrator with enhanced lateral effects (PELE) penetrating a metal target plate, breaking length of the PELE jacket and scattering radius of the fragments behind target are selected as two physical parameters to measure the fragmentation effect of PELE. A similar analysis on the fragmentation effect of PELE was conducted based on dimensional theory. Four groups of scaling model simulations were carried out using AUTODYN software, and two groups of scaling model verification tests were done. It is determined that the fragmentation effect of PELE satisfies geometric similar law through the similar theory analysis, and in the range of 800–2000 m/s impact velocity, the normalized breaking length of jacket and dispersion radius of fragments both increase linearly with the impact velocity in the simulation and test results, which proves that the fragmentation effect of PELE penetrating the metal target satisfies the geometric similarity law.
