摘要

The crack kinking effect at a sharp notch in initial stage of propagation is considered. The direct modeling of zigzag-like fatigue crack growth is carried out on the base of continuum damage mechanics concept with account of non-local fracture criteria. The results of numerical simulation are discussed and compared with the experimental data.
