The genesis of adiabatic shear bands

WebAdiabatic shear bands have been previously studied because of their importance both in metal w3rking operations (such as turning, reaming, punching, and forging) and in other pro-cesses at high strain rates (such as armor and projectile failure, and explosive forming).

WebIt reveals that as the strain rate increases, localized deformation develops gradually, and when the strain rate reaches 1.75×10 3 s −1, the deformed shear bands appear first as shown in Figure 3.3A, and as deformation proceeds, the width of the band becomes gradually narrower.

Web10 Jan 2024 · Our experimental results show direct evidence that ASB forms several microseconds after stress collapse and temperature rise reaches its maximum about 30 μs after ASB formation. This observation indicates that temperature rise cannot be the cause of ASB. Rather, it might be the result of adiabatic shear localization.
