Fatigue response of hybrid magnesium/APC-2 nanocomposite laminates at elevated temperature

As for cyclic tests we received the data of applied stress vs. cycles and plotted the S-N curves. Also, the failure mechanisms were observed. It was found APC-2 quasi-isotropic nanocomposite laminates possessed better fatigue resistance than that of the cross-ply nanocomposite laminates. Through the regression of fatigue data we proposed the semi-empirical model for APC-2 nanocomposite laminates and the theoretical model for hybrid nanocomposite laminates. Both models predicted the results of durability/life in good agreement with experimental data. The theoretical model for hybrid nanocomposite laminates was simple, conservative and precise.
