Validation of Dynamic Hardening Models with Taylor Impact Tests at High Strain Rates
This paper is concerned with the hardening behavior of 4340 steel at high strain rates from 104 s-1 to 106 s-1. Tension tests were conducted using Instron 5583, HSMTM and SHPB testing machines at a wide range of strain rate from 10-3 s-1 to 103 s-1. Three different impact velocities were performed for the Taylor impact tests to evaluate the reliability of Johnson–Cook model, modified Johnson–Cook model, modified Khan–Huang model, and Lim–Huh model at high strain rates for 4340 steel.
