Features of fatigue fracture of steels and alloys

The determination of inelastic deformation for one loading cycle at the stress level of the endurance limit is considered. A sharp drop in plasticity and inelastic deformation prior to material failure is established. The influence on these indicators of the mechanical properties of the material and its stress state, determined using temperature and structural stress concentration coefficients, is shown.
