FATIGUE DAMAGE DURING COMPLEX STRESS HISTORIES

Technical Report ·
OSTI ID:4226815

The relation between fatigue life and the relative number and amplitude of imposed cycles of stress was determined in wire specimens of 2024-T4 and 7075- T6 aluminum alloys and hard drawn steel. Agreement was excellent between the hypethesis that the fatigue life was adequately described by a two-parameter expression involving the percent of cycles at high stress and a stress interaction factor and the experimentally determined fatigue life.
