Effect of Configuration and Target Span on the Ballistic Resistance

Abstract:

Numerical simulations were carried out wherein 20 mm diameter conical nosed projectiles were hit on Weldox 460 E steel targets of varying span and configuration in order to study the influence on the ballistic limit. The effect of configuration was studied with 12 mm thick monolithic and double layered in contact target (2 × 6 mm) of 500 mm span diameter whereas the influence of target span was investigated by varying the diameter of 12 mm thick monolithic target as 100, 200, 300, 400 and 500 mm. The monolithic targets were found to offer higher ballistic limit than that of the layered in-contact target. The ballistic limit was also found to be affected by the variation in span diameter; its value was found to be 199.5, 213.9, 220.7, 226.08 and 230 m/s for 100, 200, 300, 400 and 500 mm span diameter respectively.
