Description / Abstract:
Information that provides design guidance in avoiding fatigue failures
is outlined in this SAE
Information Report. Of necessity, this report is brief, but it does
provide a basis for approaching
complex fatigue problems. Information presented here can be used in
preliminary design estimates of
fatigue life, the selection of materials and the analysis of service
load and/or strain data. The
data presented are for the "low cycle" or strain-controlled methods
for predicting fatigue
behavior. Note that these methods may not be appropriate for materials
with internal defects, such
as cast irons, which exhibit different tension and compression
stress-strain behavior.
