Fig. 4. (a) Overall view of the through-thickness fatigue pre-crack with semi-elliptical shape inserted in the numerical model (a/L=0); (b) Mode-I stress intensity factor (SIF) values, K I [Pa.m 0.5 ], calculated along the thickness of the specimen (x-axis) at six contours; (c) Mode-II stress intensity factor (SIF) values, K II [Pa.m 0.5 ], calculated along the thickness of the specimen (x-axis) at six contours; (d) Mode-III stress intensity factor (SIF) values, K III [Pa.m 0.5 ], calculated along the thickness of the specimen (x-axis) at six contours.
