摘要：
Shock-induced temperature rise of the porous liner before collapse was calculated based on the Grüneisen equation of state revised by Herrmann, effect of porosity on the shaped charge break-up time was analyzed theoretically. The stability of jets produced by shaped charges with two different porous liners was studied with flash X-ray and penetration tests. It is shown that the jet stability increases with the porosity within a certain range of porosity.
