Study on partial penetration of projectile into steel target

Study on partial embedment of projectile (PEP) is put forward with the development of modern science and technology. The outer part of PEP standing stably can form an obstacle or induce the selective object to attack it by waiting for the proper chance, or act as the loading point to realize the special application. The research on a new nose shape projectile was carried out by the numerical analysis on process of PEP and material testing of rheological behavior. Meanwhile, the main dimensionless group parameters are obtained by dimensional method. The deformation of target and energy evolution of the whole system in the forward and rebound phases of projectile are analyzed. The exploratory development work on mechanics of the PEP action was performed. Ultimately, PEP on steel target is verified by artillery experiment.
