To improve the damage efficiency of the compact terminal sensitive projectile with EFP warhead, it is vital to understand how the embedded structure (ES) affects the EFP forming performance. In this paper, the corresponding numerical investigation is focused on, where the fluid-structure interaction (FSI) method is applied and the experimental verification is employed. Based on the obtained quantitative relations between the formation performance and α (the ratio of the height to the maximum radius of the ES), the optimal design is further provided. The results indicate that: At a fixed volume, when the embedded structural length and width range 0.1-0.3D and 0.1-0.2D respectively (D: diameter of the EFP warhead) EFP forming velocity nearly keeps as a constant, 1760m/s; the height of ES can affect the detonation wave propagating range dramatically resulting in significant influences on the EFP aerodynamic shape and length-diameter ratio; under the given constraints, the EFP length-diameter ratio can reach the optimal value, 2.76 at height of ES 0.22D.
