Hugoniot and wave-profile measurements on shock-loaded stainless steel (21Cr-6Ni-9Mn)
A series of planar impact experiments has probed the shock response of 21Cr-6Ni-9Mn stainless steel targets loaded to peak stresses of 10 to 20 GPa. The impactor configuration produces a dwell time in the target (nominal thickness = 4 mm) of approx.1 s at the peak stress, followed by unloading to lower stresses through a rarefaction originating at the impactor rear surface. For each experiment, the target plate is backed by a transparent window, and a velocity interferometer monitors the motion of the target/window interface. Resultant velocity histories exhibit a distinct two-wave (elastic-plastic) loading structure from which the Hugoniot Elastic Limit (HEL), Hugoniot, shock strain rate, and shock viscosity for this alloy are determined.
