| Abstract: | The fatigue crack growth kinetics on the second portion of the fatigue crack growth diagram is described using an equation
that takes into account both the current crack tip opening displacement and the instant when the crack closure in a cycle
vanishes and does not appear until the specimen failure. This instant corresponds to the critical effective SIF range, ΔKfcl.
