• For typical honeycomb materials used in turbine casings of aero-engines to prevent blades from scraping the casing, 2 commonly used material models, the Johnson-Cook model and the honeycomb equivalent model, and the relevant calibration methods were discussed. Then the 2 models were implemented in the simulation of a honeycomb impact test, and the simulation results were compared with the test results. It is shown that, through appropriate parameter calibrations and reasonable simplifications, the Johnson-Cook model provides satisfying results, in which the damage prediction is in good agreement with the test observation. Since the Johnson-Cook model is relatively easier to be implemented with enough prediction accuracy, it is recommended for blade-honeycomb scraping analysis of aero-engines.
