Abstract

Abstract A controlled fragmentation method, by deep laser melting, for a multi-purpose projectile (penetrator) is presented, using a full-sized projectile with 1100 mm long, 148 mm diameter, and 17.8 mm wall thickness. Effects on penetration and fragmentation performance, for various laser melting parameters, are explored through penetration and fragmentation field tests. It is shown that it is possible to attain an optimal local microstructure, in the melted regions, that ensures a pre-defined fragmentation pattern upon explosion without compromising on the penetration capabilities.
