Standards for Ordnance Materials; Dynamic Fracture and Environmental Cracking Applications

Abstract

It is easy to appreciate that dynamic fracture is important when dealing with ordnance components and materials. To many, ordnance means cannons and projectiles, and that of course means a rapid load applied to both the cannon and the projectile. Because of this the effects of dynamic loading on ordnance materials has been of concern for a long time, literally for centuries. Much more recently, it has been realized that the chemical environments associated with the firing of a cannon create problems of comparable difficulty to those caused by rapid loading. Environmentally-assisted crack growth is a particular problem in cannons, because it is often present in combination with other severe loading and service conditions that are typical of cannon firing.
