Abstract EN
Numerical simulations and analysis of ballistic impact and penetration by tungsten alloy rods into composite targets consisting of layers of aluminum nitride ceramic tile(s), polymer laminae, and aluminum backing are conducted over a range of impact velocities on the order of 1.0 to 1.2 km/s.
Computational results for ballistic efficiency are compared with experimental data from the literature.
Simulations and experiments both demonstrate a trend of decreasing ballistic efficiency with increasing impact velocity.
Predicted absolute residual penetration depths often exceed corresponding experimental values.
The closest agreement between model and experiment is obtained when polymer interfaces are not explicitly represented in the numerical calculations, suggesting that the current model representation of such interfaces may be overly compliant.
The present results emphasize the importance of proper resolution of geometry and constitutive properties of thin layers and interfaces between structural constituents for accurate numerical evaluation of performance of modern composite protection systems.
