Scatter in fatigue data was treated with a probabilistic approach based on a two-parameter Weibull distribution to construct P-F-N curves. FEA predicted immediate local failure at the overlap edge in less than one cycle, whereas experiments showed gradual damage accumulation leading to global structural failure after many cycles. To resolve this discrepancy, an experimental calibration method, called CFFL, was employed. The calculated CFFL for hybrid joints was shown to increase non-linearly with overlap length and its corresponding load level. This relationship enabled fatigue life prediction without additional experiments. To validate the applicability of the CFFL calibration, additional fatigue tests at different overlap length were performed. The FEA results calibrated with CFFL showed good agreement with experimental data. The proposed approach provides a reliable basis for fatigue life prediction of hybrid joints.
