Abstract
An Armour-Piercing Fin-Stabilized Discarding
Sabot (APFSDS) is highly energetic and ballistic ammunition
used for piercing armored vehicles and battle tanks. These
ballistic rounds impart high kinetic energy to the target that
involves high strain rates and melting temperatures. The lethality
of ammunition is tested against RHA depth it would penetrate.
This paper discusses the terminal ballistic aspect of the
penetrator and presents the study of design parameters for an
APFSDS to achieve optimal penetration. The trend of
penetration depths across the range of length-to-diameter ratios
is presented. A tungsten alloy APFSDS is tested against Rolled
Homogenous Armour (RHA) via FEA simulations. A simplified
penetrator model is created and parameterized in Design
Modeler. Explicit dynamics numerical schemes are used.
Johnson-Cook strength and failure models are chosen along with
Mie-Grüneisen state of equation model. ANSYS Autodyn solver
is used for simulating the impact.
