摘要：

The plastic deformation behavior of nickel-iron alloy Inconel 718 in shear was measured at strain rates of 0.01 s(-1) and up to 3000 s-1 with a quasistatic torsion machine and a split torsional Hopkinson bar, respectively. The measurements were analyzed to determine Johnson-Cook parameters and obtain material constitutive information needed for finite element simulations. (c) 2007 Elsevier Ltd. All rights reserved.
