4. Summary

The mathematical model has been developed for investigation of the subcritical growth period of fatigue physically or mechanically short cracks near the tip of smooth stress risers. The correctness and preciseness of the proposed model are validated through comparison with known experimental data. Contrary to the known models, the proposed model provides correct results for a crack of zero initial length.
