Plastic Flow Behavior of Inconel 718 Under Dynamic Shear Loads


Kobayashi, T., Simons, J. W., Brown, C. S., & Shockey, D. A. (2008). Plastic flow behavior of Inconel 718 under dynamic shear loads. International Journal of Impact Engineering, 35(5), 389-396.


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.
