title = "Study on shock initiation of cylindrical-shell charge impacted by spherical fragment",
abstract = "The numerical simulation of the interaction between spherical tungsten fragments and cylindrical Comp-B explosive covered by steel casing was carried out by using AUTODYN-3D software. The influences of the fragment impact angle θ and cylindrical charge curvature radius r on the impact initiation characteristics of the explosive are analyzed, and the critical initiation velocity of cylindrical-shell charge (CSC) is obtained. The results show that the impact initiation mechanism of CSC coincides with that of planar-shell charge (PSC). For CSC, the critical initiation velocity increases exponentially with the increase of the sine value of θ and increases nonlinearly with the increase of r, which indicates that the CSC is easier to detonate. In addition, another high-precision simulation software SPEED was used to carry out the initiation process of the insensitive explosive PBXN-109 under the impact of fragments, hoping to provide a reference for further study of impact initiation in reality.",
