Computational Model of Initiation of Fatigue Cracks Near Hydrogenated Notches

  • O. E. Andreikiv
  • D. V. Rudavs’kyi


By using the energy approach of fracture mechanics, we develop a computational model of initiation of a fatigue microcrack near the tip of a notch in a hydrogenated material. The influence of hydrogen on the fracture process is modeled by the decrease in the critical strain in the material according to a linear law. We deduce a relation for the period of initiation of fatigue microcracks near the hydrogenated notch tip. The numerical results are satisfactorily agreement with the available experimental data.
