| Abstract: | The influence on perforation process caused by steel plate in Concrete with Steel Plate structure was mainly discussed. According to the deformation and breakage of Concrete with Steel Plate medium in multistage and the difference of energy in both time and space, the Concrete with Steel Plate model of deformation and breakage was established, parameter of resisting force from steel plate was confirmed, and therefore, the movement equation of projectile and perforation block was presented. The conclusion was obtained that the penetration depth of projectile will deminish when joined with steel plate. |
