摘要

•Entropy based fatigue evaluation method is applied on spot welded joints.•The relationship between entropy, load, and number of cycles is formulated.•The proposed fracture fatigue entropy-based F-N curve is similar to three-parameter power F-N curve.•The maximum relative error of the fatigue limits obtained by different methods is 10.9 %.
