3. Materials data In the following chapters, the basic fracture mechanical properties of used materials for criteria are introduced. The mixed mode stress intensity values ( K I and K II ) are introduced from the experimental data that was obtained in previous laboratory campaigns. The precise description of materials could be found in mentioned references.  C 50/60 (Seitl et al. 2018), Table 1 C 50/60 (a/R=0.4) Specimen n.o. angle α [°] K I [MPamm 1/2 ] K II [MPamm 1/2 ] C50/60_6_01 0 26.033 0.001 C50/60_6_02 0 33.647 0.001 C50/60_6_03 0 32.666 0.001 C50/60_6_04 5 25.520 10.947 C50/60_6_05 10 22.068 21.420 C50/60_6_06 10 23.830 23.130 C50/60_6_07 15 13.543 25.380 C50/60_6_08 15 17.281 32.387 C50/60_6_09 25.2 0.005 42.989 C50/60_6_10 25.2 0.005 41.056
