Abstract
During the ballistic event of projectile being fired in a cannon barrel, the barrel undergoes multiple forces that push the structure to its limits. The greatest of these forces is the extreme pressure the barrel experiences in just a fraction of a second. The pressures exerted on the bore of the cannon generate large stress concentrations and degrade the structural integrity of the bulk material. Coupled with the pressure effects, large thermal stresses are encountered due to the immense thermal loads of the ballistic events. The ability to predict the dynamic response to these events will greatly increase the ability to understand and limit the effects they have on the cannon barrel. This paper will explore the temperatures and three dimensional stresses of a cannon barrel using finite element based computer simulation. The temperature and stresses will then be compared to previous research and experimental results to determine the validity of the model. After the model is verified, it will play a key factor in predicting the dynamic response of a cannon barrel to the various ballistic effects of the different round types used today.
