Abstract : While usually not intended, yielding during firing probably occurs in many shells on their interior surface in the vicinity of the rotating band. Nevertheless, except for instances where the accompanying deformation may cause a malfunction in an internally carried device, such yielding may be considered a part of 'good' design. The purpose of this investigation was to attempt to develop a foundation for procedures whereby the shell designer can: (1) predict post-yield deflections in shells in the region beneath the rotating band, and (2) determine, a priori, the magnitudes of rotating band pressures for a particular shell-band-gun system.
