Abstract: The presented work discusses performing a V/L (Vulnerability/Lethality) analysis on an armored tank based on an RHA (Rolled Aomogeneous Armour) equivalence. It is shown how the approach works using small examples verified with hand calculations. Other more complex examples include a set of welded plates protecting a HYBRID III 50 Percentile Male ATD (Anthropomorphic Test Device). Considered response parameters are the VAA (Vulnerable Area Assessment) damage maps, expected protection capability plot, and damage area fractions. Furthermore, different V/L analyses of the Russian T-80 tank are displayed. It is illustrated how to apply the concept of explicit finite element models to find the critical RHA equivalent armor thickness at normal impact. It is done with terminal ballistic models for three materials: RHA, Aluminum 5083-H116, and Armox 500T.
