摘要：
Numerical simulation for the initiation or ignition of explosive with aluminum shell was carried out following the Lee-Tarver initiation model of the Autodyn-2D code when it was impacted respectively by sphere or column form fragment. The influence on charge detonation of the shape and velocity of fragments, and the thickness of aluminum was analyzed. By means of the up-down method, the critical detonation velocity of Octol was obtained.
