R. Citarella et alii, Frattura ed Integrità Strutturale, 34 (2015) 514-523; DOI: 10.3221/IGF-ESIS.34.57 520 Figure 12 : SIF results along selected crack fronts for the combined bending + press fit load case . DBEM Crack propagation for the combined bending + press fit load case The crack propagation simulation is splitted in 16 steps, with an average crack advance at each step equal to 0.5 mm, and with a fully automatic remeshing at each crack advance. SIFs along the crack fronts for the combined bending + press fit load case are plotted in Fig. 12: if initially there is a faster crack growth in the depth direction, after few steps the reverse happens with a faster crack advance at breakout points.
