Fracture Damage and Failure of Cannon Components by Service Loading

Abstract

The types of crack-related failure which occur as a result of cannon firing are reviewed. A very severe brittle fracture of an early cannon is resummarized. The failure processes typical of cannons are described, including crack initiation due primarily to high temperature exposure, fatigue crack growth due to the cyclic pressurization of firing, and final fast fracture through the wall of the cannon tube. The effects of chemical environment and residual stresses on the failure processes are discussed.
