N2 - Johnson-Cook (JC) flow stress and failure parameters have been specifically tailored for high-density polyethylene (HDPE) pipe material from mechanical monotonic tensile tests covering various strain rates. The calibrated constitutive model underwent successful validation under a different loading condition resembling drop weight impact tests, including impact speeds of 2, 3 and 4 m/sec. Numerical simulations using Abaqus commercial software demonstrated the accuracy of the JC material model, with validation based on the 2 m/sec speed revealing dishing (indentation damage) in the HDPE plate, and the higher velocities (3 and 4 m/sec) validating the JC damage model with penetration damage. The material model exhibited strong validation, showcasing excellent agreement between experimental impact tests and numerical predictions across all testing conditions.
