Summary:The penetration equations of the FATEPEN2 engineering code have been updated to include behavior of large length-to-diameter ratio rods into spaced plate arrays. The changes were validated with light-gas gun experiments conducted at the Naval Research Laboratory to determine the effects of pitch and yaw on long-rod penetration. These experiments were modeled using the CTH hydrocode to simulate rod impact and interaction with the plate array. Numerical and experimental data for three tests were compared directly, and the discrepancies were analyzed. The analysis led to the conclusion that problem resolution is critical to the success of the calculations.
