✦ Synopsis

The effect of rest periods on fatigue life was investigated.

Small size specimen and constant load amplitudes were used with a new developed fatigue testing machine in alternating bending. Rest periods of 1.5 min were introduced after each half cycle. The cycling rate was 0.25 cpm. Comparative tests on specimen tested without rest periods showed a substantial increase in fatigue life due to rest periods.

Centrally cracked specimens of JIS SM58Q and I-IT80 steels were fatigued. The fatigue crack growth rates, da/dn, and the stress intensity threshold levels, AK,, were measured over the range of stress ratio, R, from -1 to 0.8 by the use of an automatic method of continuously decreasing stress intensi
