Abstract:
Fatigue curves are costly and time-consuming to generate by actual testing. Fortunately, there are theoretical techniques available for approximating the shape of a fatigue
curve. Two such short cuts, the "method of universal slopes" and the "four-point correlation" method, have been known for years. Each, however, needs lengthy calculations,
from data that are not always readily available.
A
n alternative method, based on "four-point correlation" theory, allows
fatigue curves to be constructed using only handbook data. This technique correlates reasonably well with real fatigue data for most steels, magnesium, aluminum, and
copper. It may work for other metals, too.
