Mechanical structures are usually subjected to an atmospheric environment, where the temperature and the humidity vary depending on the place, the season and the time of day. In order to examine the effect of atmospheric conditions on the fatigue life distributions, statistical fatigue tests in rotating bending were carried out on carbon steel for machine structural use (JIS:S35C) under the following five conditions; 1) 35℃-WET, 2) 35℃-DRY, 3) 20℃-WET, 4) 20℃-DRY and 5) 3℃-Room Air. Based on the experimental results, it was found that the temperature was the predominant factor in the fatigue life distribution rather than the humudity. The temperature dependence of the fatigue life distribution was then analyzed, and an analytical procedure was developed to evaluate the effect of the atmospheric conditions on the fatigue life distribution.
