Abstract: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 . Wi… Show more
