“…For test specimens with a well defined geometry, the effect is manifested through differences in crack propagation rates between thin and thick samples with throughthickness cracks or tunnelling effects in samples with surface cracks [33][34][35][36]. Crack tunnelling during cyclic loading could be related to the amount of crack closure present.…”

“…For example, the influence of the stress ratio 27 is directly related to the strain retardation with respect to the imposed stress. and fracture toughness [38][39][40] since it is a common opinion that the fatigue strength is reduced as the R-ratio increases. The R-ratio is of great importance in fatigue testing [28][29][30][31][32][33][34][35][36][37] and refers to crack formation/propagation at different fatigue regimes (LCF, VHCF etc.)…”
