摘要

A new crack closure analytical model was used to calculate the fatigue crack opening stresses for two cracked geometries (single-edge-cracked tensile plate and single-edge-notch-cracked tensile plate) with a larger crack length at two stress ratios. The results were combined with the previous ones to further study the crack closure behavior for four cracked geometries with different crack lengths under plane stress condition. The results showed that the crack closure behavior is obviously affected by specimen geometry, stress ratio and finite width of specimen.
