This memorandum presents a mathematical model to assess fragment hole area based on projectile impacting a target as a function of its velocity. Fragment Simulating Projectiles FSP of different mass and velocity were used for experimental trials with witness packs WP. The analyses were performed with the latest versions of DeCaM Debris Characterization and Modelling software and WPAS Witness Pack Analysis System. The hole growth equation developed is linear and includes fragment mass and velocity as parameters. This memorandum also presents other existing models and verifies their validity with experimental data. Finally, Velocity Threshold Curves VTC related to Al- 1100 WP are presented as well in order to estimate fragment velocity from fragment mass, which is calculated using the fragment hole diameter recorded in the WP.
