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