包覆式爆炸成型复合侵彻体成型与侵彻过程的数值模拟

In this paper, a typical Charge Structure of wrapping explosively formed compound penetrator (WEFCP) model is established in AUTODYN-2D code. The formation and penetration process of WEFCP are calculated and analyzed. Based on the numerical simulation, the formation process has three phases: compression, stretching and breaking; and the penetration process includes two phases: perforation of precursor penetrator and expanding penetration of main penetrator. The feasibility of WEFCP mechanism is validated by contrastively analyzing wrapping part (inner core) pressure during formation and penetration process.
