Monotonic and Fatigue Characterizations of Metals 820679

Monotonic and cyclic properties for metals are reviewed. Conventional stress based fatigue characterizations of S-N curves and mean stress plots are illustrated. Strain based mechanical hysteresis concepts are used to express cyclic stress-strain properties, and fatigue properties when combined with fatigue life data. These properties are useful for a computer based materials data file for engineering applications.
Cyclic deformation behavior for cyclic creep and stress relaxation is illustrated.
A fatigue notch characterization is given based upon Neuber’s Rule.
