Modeling of Barrel/Projectile Interaction in a Rotating Band

Abstract

The ABAQUS program was used and a refined finite element mesh was chosen to complete the modeling of the barrel/projectile interaction in a rotating band. The calculations for the engraving processes proceeded until the projectile had passed completely through the forcing cone in the land and groove. The axially symmetric cases were considered and the elasticity of the tube and projectile was neglected. Sliding friction was considered and the copper band was either elastic-plastic or ideally plastic. The magnitude and distribution of the contact pressure between the band and the tube were obtained during and after engraving. For the first time we have observed the opening of a gap between the band and the bore after engraving was completed, even when we observed full contact in the forcing cone.
