    • Abstract. High strength 1565 aluminum alloy was tested within impact velocity range of 250-750 m/s in two schemes of shock loading: (i) under uniaxial strain conditions and (ii) in high-velocity penetration. The combination of load regimes allows the ...
    • Keywords: aluminum alloy, spallation, high-velocity penetration, multiscale deformation, macro-meso momentum exchange, velocity oscillations

    • Fig. 3. Penetration cavern in 1565 aluminum alloy at the impact velocity of 577 m/s
    • Within impact velocity range of 250 - 750 m/s the strength behavior of alloy proves to be opposite – when resistance to penetration increases, the spall strength decreases.
    • The defect of particle velocity plays a role of a control parameter in the dynamic deformation of the material. It defines the transition from one scale to another.
    • The transition from one structural scale to another is realized through the excitation of mesoscale oscillations resulted from the back coupling between deformation processes at the macroscale and mesoscale.
    • The maximum dynamic strength is realized in the impact velocity range where the velocity defect equal to the velocity variance.
