Show other versions (1)

The work is devoted to the study of the damage accumulation in iron under gigacyclic fatigue (VHCF) regime. The study of the mechanical properties of the samples with different state of life time existing was carried out on the base of the acoustic resonance method. The damage accumulation (porosit...

The damage accumulation (porosity of the samples) was studied by the hydrostatic weighing method.
