Abstract: | A group of theoretical models has been developed for analyzing transient dynamic response to filled metallic cylindrical shells
impacted by flat-nosed missiles at normal obliquity on the basis of the analogy modeling method of beam-on-foundation. It
can be used for solving the global deformation and the local failure of cylindrical shells in the impact process. The ballistic
limit speed and impact response history have been calculated by this group of theoretical models, and the inner pressure effect
on the ballistic limit speed and some parameters are discussed at length. The quantitative relationship between internal pressure
and the ballistic limit speed and some significant conclusions have been obtained, which are basically identical with previous
experimental results.
