Analysis of Engraving and Wear in a Projectile Rotating Band

Abstract

A large deformation analysis of the engraving process and wear in a projectile rotating band is considered by using the finite element program ABAQUS. The tube and the projectile are assumed to be rigid. and the bore of the tube is assumed to be smooth and axisymmetric. An elastic-plastic material model is chosen for the copper band, which remains attached to the projectile, and an appropriate coefficient of sliding friction is chosen. The magnitude and distribution of the contact pressure between the band and the tube are obtained during engraving. The band pressure is large with severe plastic deformation occurring in the band.
