A continuing program to determine the fatigue characteristics of gun barrel materials is intended to lead to the prediction of fatigue damage in gun barrels and will facilitate the development of improved barrel materials. The outside surface temperatures of an M60, 7.62mm, gun barrel were measured during the test firing at various locations, and the temperatures across transverse sections of the barrel were calculated. The data were analyzed to study the effect of prestress on fatigue properties and to develop stress life curves for design purposes.
