An analytical mechanical model is developed to predict the room temperature spallation
behavior, including the separation nucleation, stable and unstable growth, and final spallation
and kinking off, of α-alumina films grown by oxidation on Fe-Cr-Al alloy. The predictions
from the developed model are compared against experimental results and excellent
agreement is observed. The work reveals a completely new failure mechanism of thin layer
materials.
