The Research on Fragmentation of Tungsten Heavy Alloy Fragile Material after Penetration
Based on the Kipp fragmentation model, an analysis has been developed to describe the relationship of diameter of fragments and impact toughness, impact velocity as well as projectile-target acoustic impedance when tungsten heavy alloy fragile material penetrating the metal plates. The dynamic penetration experiment for tungsten alloy fragile material with different component against the target is carried out. The size and the distribution of the fragments after penetration are obtained. Theoretical predictions show good agreement with the experimental results on the condition of low impact toughness. Analysis model and experimental results offer a theoretical reference for the engineering design of tungsten heavy alloy fragile projectile.
