- W2923555770 abstract "The explosively formed projectile (EFP) attains maximum velocity which attenuates to stable velocity during the flight. Different parameters (pressure, stability, compression etc.) are calculated using liner materials MS, Cu, Al, Fe and Ta at these velocities. For instant Al has highest velocity and shorter time to get stable velocity so it would be useful for large standoff applications and in tandem warhead with contact fuse as a precursor cone where quick response is needed. The Ta EFP has larger diameter because of low thermal softening exponent, high density and larger hardening exponent which indicates its application where wide crater in the target is required. The Fe has diameter very close to Ta that is why, Fe is very economical alternative for same application. The temperature generated within the Ta EFP is highest, so Ta can also beused in the applications where hot fragments are required. The L/D ratio for Cu EFP at stable velocity is highest which supports maximum penetration. The MS is most reliable or stable liner’s material due to minimum divergence. So this material would be effective replacement of Fe in the multiliner EFP with Ta aspenetrator and Fe as stabilization base. The compression and shock pressure generated in MS EFP are highest, which means MS is most shock absorber material. Each liner material has different velocity profiles due to density gradients. The velocity decaying rate of the liner material is inversely proportional to its density means higher the density lower is the decaying rate. Other material parameters also have infinitesimal effect on the velocity decaying rate." @default.
