Some Experiments on the Fatigue Life under Double and Triple Stresses

概要

論文の詳細を見る
Fatigue lives under cumulative stresses were investigated under double and triple stresses on carbon steels (0.07%C, 0.25%C, 0.47%C). The results were as follows : (1) In a low carbon steel (e.g. 0.07%C, 0.25%C), the fatigue life was prolonged by secondary and tertiary stresses regardless of whether they are higher or lower than the primary stress. (2) In a high carbon steel (e.g. 0.47%C), however, the fatigue life was shortened by the secondary and tertiary stresses when they were lower than the primary stress. But the fatigue life was prolonged by the secondary and tertiary stresses when they were higher than the primary stress.
