Paper Title:
Dynamic Analysis on the Rotating Band’s Engraving Process
  Abstract

The Johnson-Cook yielding criteria model, the initial damage model and the progressive damage and failure constitute model have been introduced into the constitutive equations of the rotating band. By using the penalty function method, the dynamic contact model has been introduced and an explicit dynamics finite element model has been established. The process of the rotating band impacting the throat bore was molded based on the elastic-plastic contact finite element theory. The rotating band pulling in and impacting the throat bore was simulated by the numerical computation. The dynamic responses of the rotating band and the projectile were obtained. And the stress distribution of the throat bore was studied. The influences of the engraving process on the interior ballistics were studied through the numerical computation.
