A 'C'-Shaped Fracture Toughness Specimen from the Wall of a 5-in./54, Mk 64, Naval Projectile

Abstract

This Report examines the suitability of a 'C'-shaped specimen configuration for the measurement of the fracture toughness of an artillery projectile manufactured from a high fragmentation steel. For this investigation a conventional shell steel, taken from the Australian 5-in./54 HE naval projectile, has been heat treated to fracture toughness states approximately corresponding to those of the new-generation steels used in high fragmentation projectiles. The practical aspects of specimen preparation and testing have been assessed in this work.
