Abstract
Quasi-static pressure is one of the most important damage loads by semi-armour-piercing warhead of anti-ship missile. Based on the chemical reaction and the state equation in explosion, a formula for prediction of the quasi-static pressure was presented and verified with the model test. Difference of the quasi-static pressure between presence and absence of oxygen was discussed. The results show that: (1) explosion in a cabin is quite different from that in the free field, besides the multiple reflected shock waves, there is quasi-static pressure in the cabin; (2) the state equation based calculation of quasi-static pressure has certain ability in prediction; (3) the effect of subsequent combustion supported by oxygen is very important in the formation of quasi-static pressure. The research may provide effective support for revealing the mechanism of damage protection and design of the cabin.
