Title:Fatigue damage during complex stress histories final report
Author(s):Liu, H.W.; Corten, H.T.
Subject(s):Fatigue Damage
Complex Stress
Abstract:The influence of complex stress histories on the fatigue life of members has been investigated to determine the relationship between the fatigue life and the relative number and amplitude of imposed cycles of stress. A physical model of fatigue damage was formulated in terms of the number of damage nuclei initiated by the highest applied stress and the propagation of damage by all subsequent cycles of stress. Based on this physical model, a mathematical equation was derived that related the fatigue life to stress history. Further interpretation of this equation was made by an alternative hypothesis.
