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.
