Soft tissue simulants are used in ballistic testing as a tool for capturing the interaction projectiles have with living tissue. No internationally agreed standard exists for the preparation of such tissue simulants; a factor that has led to questions regarding reliability and reproducibility of results presented in the open literature. A calibration method for 10 % gelatine has been suggested utilising low velocity projectiles [1]. However, recent work has suggested that gelatine is strain rate sensitive [2]. Therefore it may be more appropriate to test at velocities representative of the projectile under investigation. This paper presents a modified method to assess the differences in penetration depth in three simulants. Non-deformable ball bearings (BBs) of similar diameter to ammunition of interest (5.5 mm BBs, 5.56 mm × 45 mm) at a range of velocities representative of different engagement ranges (150 m/s, 250 m/s, 500 m/s, 750 m/s and 1050 m/s) were used.
