Abstract

It is postulated that a representation that would provide necessary and sufficient information on fatigue damage must be based on the statistical distribution of the peak values. Statistics affecting fatigue life are examined and a convenient method for estimating their numerical values is demonstrated and illustrated by an example including four different spectra. The proper specification of a random load is discussed and some conclusions regarding the planning of random fatigue tests are presented.
