Yactor, R J

A shock initiation model was developed for the initiation of bare or clad explosives impacted by flat or hemispherical-tipped projectiles. The model requires Hugoniot data for the unreacted explosive, cladding material and projectile material, and the shock run distance to detonation as function of the shock pressure imparted to the explosive. Model results are compared to experimental data for flat and hemispherical-tipped steel projectiles impacting bare and clad PBX 9404 explosive.
