Abstract: Liquid cooling methods are often used for thermal management of a large caliber gun barrel. In this work, transient thermal analyses of midwall-cooled and externally cooled gun barrels were ...

Abstract: An accurate modeling of gun barrel temperature variation over time is important to assess wear and the number of shot fires needed to reach cook-off. Using lumped parameter methods, an internal ...

Abstract: It may be necessary to provide a radial opening such as gas evacuator holes, or an opening to operate the unlocking of the bolt mechanism by means of exhaust gases, in a gun barrel, which ...

Abstract: A multi-linear kinematic, two dimensional finite element model incorporating Bauschinger effect, developed using ANSYS commercial software is used to determine the effect of machining both at the ...

Abstract: Analytical and numerical stress analyses of the autofrettage process have made great strides in the last few years. The major challenge is no longer the stress analysis process but the ...

Abstract: Swaging is one method of autofrettage, a means of prestressing high-pressure vessels to increase their fatigue lives and load bearing capacity. Swaging achieves the required deformation through ...

Abstract: High-pressure vessels, such as gun barrels, are autofrettaged in order to increase their operating pressure and fatigue life. Autofrettage causes plastic expansion of the inner section of the ...

Abstract: High-pressure vessels are autofrettaged to introduce favorable, compressive, residual stresses around their inner diameters. The efficacy of autofrettage is limited by a phenomenon called the ...
