Returning to the observed fact that most of the temperature rise occurs during the
latter stages of the fatigue life , other tests have been reported wherein
intermittent rest periods were interjected into the cyclic history of the sample . In

While this reinforces the contention that thermal failure is primarily associated
with a rapid temperature rise occurring during the latter stages of fatigue life , the
use of fatigue data based on periodic rest period testing are certainly not ...
