Normal and Oblique Impact of Cylindro-Conical and Cylindrical Projectiles on Metallic Plates

“…These localized bands of deformation, termed concentrated or adiabatic shear bands (References [17][18][19], are the result of large temperature gradients that occur in bodies loaded at very high strain rates when the rate of local heat production by mechanical work exceeds the rate of dissipation.…”
