Journal of Applied Mechanics and Technical Physics Aims and scope

Abstract

Tests on backward spalling of 38KhN3MFA structural steel, D-16 aluminum alloy, M-2 copper, 02Kh18K9M5-VI maraging steel, KhN75VMYu alloy, beryllium, and other materials show that spalling strength correlates with the threshold of structural instability of a material to compression at the leading edge of the compression pulse. It is shown that the threshold of structural instability to compression obtained in experiments on uniaxial deformation of flat targets determines the strength of resistance to high-velocity penetration in the Alekseevskii–Tate model.
