Structure of a shaped jet formed in an oblique collision of flat metal plates
The structure of a shaped jet formed by a high-velocity oblique collision of flat metal plates is studied. It is shown that a compact shaped jet is formed in the case of a symmetric oblique impact under conditions of the experiments conducted (both plates are impinging at an angle to each other); a dispersed shaped jet is formed in an asymmetric oblique impact (the impinging plate hits a stationary plate at an angle). The exception is metals that have a high dynamic strength (uranium or tantalum). In the regime of loading, when the contact-point velocity is smaller than the velocity of sound, a compact jet is formed in an oblique collision of plates.
