Abstract
The fatigue behavior of a high‐density graphite was investigated in reverse bending up to 5×108 cycles at room temperature. Fatigue life was analyzed statistically, using a Weibull distribution and a homologous stress. The homologous stress is the ratio of applied stress in fatigue to the expected first‐cycle strength. The first‐cycle strength was calculated from bending tests of similar materials or “mate” specimens, using the Weibull statistical strength theory to correct for the significant size effect. Homologous stress gives an essentially invariant fatigue correlation for many graphite grades and may be used to estimate fatigue life under a wide variety of operating conditions. The practical endurance limit for graphite corresponded to a homologous stress of about 47%.
