|a Results are presented of tests on bare and alclad 24S-T3 aluminum-alloy specimens at 12 and 1000 cycles per minute to determine effect of frequency of loading on fatigue strength. The number of cycles to failure varied from about 150 to over 10,000,000. Fatigue strengths of both materials were slightly lower at 12 cycles per minute, but a quantitative estimate of effect of low-frequency loading cannot be made because effects are small compared with observed scatter.
