Similarity Law Study of Shaped Charges Penetrating a Concrete Target
In order to study the similarity law of penetration of concrete targets by shaped charges, penetration tests of concrete targets with different sizes of shaped-charge jets were carried out, and the prototype and the model projectiles met the similarity law with a simulation ratio of 1:1.5.

| description | In order to study the similarity law of penetration of concrete targets by shaped charges, penetration tests of concrete targets with different sizes of shaped-charge jets were carried out, and the prototype and the model projectiles met the similarity law with a simulation ratio of 1:1.5. LS-DYNA finite element software was used to simulate the tests, and the accuracy of the ALE algorithm, fluid–solid coupling algorithm, material model, equation of state, and corresponding material parameters was verified. Numerical simulations were further conducted for the different types of shaped-charge jets (jets, rod jets, and explosively formed projectiles) formed by different liner angles penetrating into the concrete target, and the results show that the shaped-charge jets basically meet the similarity law when penetrating concrete targets. |
