The substantiation of fatigue crack closure corrections is disputed, based on the closure stress definition. The ΔKeff equation lacks a physical explanation. An inconsistency is observed between the opening stress Sopphen as used by this equation and the physical opening stress Sopphys. This Sopphys is related to Sopphen through an energy equivalent area approach. Furthermore, an elastic spring model is used as a physical approach to crack closure effects. An FEA approach generates Sopphys values, which are reworked into Sopphen. This physical model agrees well with existing closure corrections, and is able to provide a physical explanation for their necessity.
