Variations on a critical distance theme

We investigate how the fatigue limit of notched specimens calculated with the Theory of Critical Distance (TCD) changes when variations in the value of the critical distance itself are considered. We motivate our study by showing how attempts at introducing a plastic zone correction in the derivatio...
