Abstract
Newly developed grips and machine elements are described for fatigue loading under direct stress (tension-compression) ratios of alternating to mean stress from zero to infinity. Data are presented to indicate the uniformity of stress distribation possible with these grips end accuracy of the average stress. Dynamic creep, rupture and ductility data are reported on N-155, s-590 and Vitallium at 1350 and l500 F. under direct stress combinations from static to reversed loading. Stress range diagrams (alternating stress versus mean stress) are presented to indicate the stress combination which will produce rupture and various degrees of creep in 5 to 1500 hours. Per cent elongation data are analyzed in terms of alternating- to-mean stress ratio and stress magnitude, and it is shown that both are significant variables. Elongation up to the start of third stage of creep is also analyzed in terms of stress ratio and stress magnitude and only stress magnitude was found to be significant. The implications of these findings are discussed.
