Effect of Material Mass Distribution on The Life of Small Arms Barrels

Abstract

This report covers FY75 efforts on a project entitled, 'Effect of Material Mass Distribution on the Life of Small Arms Barrels.' The objective of this project is to develop a semi-empirical technique for determining gun barrel wear (or erosion) as a function of barrel material properties, wall thickness (or ratio) and firing rate. The past years task involved analytical design of test specimens (barrel geometries) for firing experiments wherein regression analyses will be performed in the determination of the effect of mass distribution on barrel life. A useful design tool applicable in the optimum design of gun barrels was developed with the addition of a CALCOMP plot routine to an existing implicit finite difference computer solution. Examples of these plots are given as part of the results for the parametric barrel specimen design study.
