Description
Initiation and development of adiabatic shear bands in explosively pre-shocked 304 and 316L stainless steels was investigated to quantify the influence of shock prestraining on the onset of shear localization. Forced shear tests on hat-shaped specimens were conducted using a compressive split-Hopkinson pressure bar. The shear localized behavior under the forced shear condition in these preshocked materials was examined. Shear-band initiation was found to be very sensitive to the preshocked microstructures, especially to the strong interactions among defects such as deformation twin networks. The microstructures of shear bands were characterized using transmission electron microscopy(TEM). Dynamic and quasi-static recovery was verified to be a dominant mechanism in the formation of the ultra fine substructures within the shear bands generated in these preshocked steels
