In this paper, LS-dyna software was used to simulate the charging process of cylindrical shell when EFP has different angles, and some interesting phenomena and laws were found. Cylindrical elastic wave σ r was generated when the cylindrical shell was impacted by EFP. The cylindrical elastic wave σ r was correlated with the time required for the cylindrical shell charge to be successfully detonated. When the EFP warhead penetration Angle θ ranges from 0° to 10°, the σ r increases linearly with (cosθ) -1/2 . With the increase of θ, the tangential velocity v y had an obvious effect on the impact of EFP on the cylindrical shell, and the linear relationship between the elastic wave σ r and (cosθ) -1/2 does not change. When the θ was greater than 45°, EFP could not successfully impact and detonate the cylindrical shell charge. The EFP velocity was measured by velocity measurement method with an error of 1.3%. The experimental results have strong similarity with the simulation results, indicating that the parameters of the numerical simulation model have good reliability.
