Abstract Using AUTODYN software to carry out numerical simulation, the “up-down” method was used to calculate the initiation velocity threshold of composition B shielded by 6 mm/9 mm thick 45 steel cover plate impacted by 10 g tungsten alloy spherical fragment. According to the Richard M. Lloyd and Jacobs-Roslund model equations, engineering calculations under the same target conditions were carried out. The results show that the velocity threshold of 10 g tungsten alloy spherical fragment to detonate 6 mm/9 mm thick 45 steel shielded composition B is 2 100 m/s and 2 200 m/s respectively, and the calculated results based on Jacobs-Roslund model equation are more consistent with the numerical simulation results. The conclusion of this paper can provide a basis for the lethality design and assessment of anti-missile warhead.
