On the Uniaxial Compression Testing of Metallic Alloys at High Strain Rates: An Assessment of DEFORM-3D Simulation

In this study, the challenges associated with conducting high-strain rate uniaxial compression testing experiments are highlighted. To address these challenges, DEFORM-3D simulation was explored as an alternative approach to experimental testing. Previously established constitutive constants obtained from low strain of three titanium (α + β) alloys were used input codes. From results, peak flow stress values close experimentally at (0.1 10/s) and high (20 50/s) rates. For considered in a discrepancy ~20% 10/s rate. The difference for rates less than or higher is within acceptable limits. limitations using simulations
