In order to investigate the effect of explosive charge shell materials on blast effect,the blast effect of explosive charge with different shell materials in air and concrete target is researched by means of numerical simulation and experimental investigation.The results show that under the same explosive charge,the peak overpressure caused by the detonation of explosive charge with composite material shell is higher than that with D6A steel shell.Because of no fragment generated in the case of explosive charge with C-fiber shell,the distant target is not affected by the fragments effect.However,blast fragment effect is distinct in the case of explosive charge with D6A steel shell.According to the blast effect in the concrete target,the explosive with C-fiber shell is superior in the matched impedance as well as detonation propagation to the one with D6A steel shell.Under the condition of the same explosive charge,the effective energy produced by the detonation of explosive with C-fiber shell is bigger than that with D6A steel shell.Results of explosion test conform to the numerical simulation.
