Martin	Instrumented anvil-on-rod tests for constitutive model validation and determination of strain-rate sensitivity of ultrafine-grained copper	2007.0	8	.pdf	application/pdf	4845	823	75	Anvil-on-rod impact tests were performed on as-received (cold-rolled) OFHC copper rods and copper processed by 2or 8-passes of equal sed to generate free surface velocity traces and transient deformation profiles for comparison with the experimental data. xperimental results with AUTODYN simulations provided a means for extracting the strain-rate sensitivity of copper as a function of grain size. eywords: Strain rate sensitivity; Grain size effects; Dynamic deformation; Ul The unknown strain rate sensitivity constant, C, was generted by fitting the simulated free surface velocity trace to that Quasistatic 0.2% offset flow stress values for ECAP specimens tested in compression at two different (quasi-static) strain rates Transient dimensions of the 8-pass ECAP specimen during deformation obtained from high-speed digital images during the experiment and from simulations at Transient dimensions of the 8-pass ECAP specimen during deformation obtained from high-speed digital images during the experiment and from simulations at	./cache/work_soaejc7zmjffpfmmfglhixg23q.pdf	./txt/work_soaejc7zmjffpfmmfglhixg23q.txt
