A. Shanyavskiy, Frattura ed Integrità Strutturale, 25 (2013) 36-43; DOI: 10.3221/IGF-ESIS.25.06 42 nano-structure with their rotation and spherical particles forming. 2. It was considered quantum-mechanical nature of metals fatigue cracking on nano-scale level and shown that crack increments in loading cycle have to be strongly expressed in accordance with introduced expression. 3. Simply equation was considered for subsurface cracking description and number of cycles’ estimation. It can be used in failure analyses of in-service cracked structures.
