Based on the characteristics of shock wave which are produced by spherical projectiles hypervelocity impact on nitrogen-filled pressure vessels, apply ingone-dimensional shock wave theory and numerical simulation method, at the condition of the debris clouds is completely ablated, the process of shock wave propagation in the gas is analyzed, and model of shock wave propagation is built. The law of shock wave propagation, the pressure of shock wave and the pressure pulse duration are obtained. The result shows that at the same impact velocity, the pressure of shock wave is increasing with gas pressure and projectile diameter. Fracture of pressure vessels impacted by hypervelocity projectiles with a diameter less than 3mm is governed by inflation pressure for projectile impact velocities of 7 km/s.
