Abstract
Strain controlled constant amplitude and variable
amplitude fatigue tests were performed for 316 NG
stainless steel in PWR water 320 C. The environment
reduced fatigue life as predicted. Variable amplitude
test results indicate a further reduction in life by a
factor of 5, which is greater than expected. Variable
amplitude straining in EPR environment resulted to
specimen failure before the fatigue usage factor
according to the ASME III design curve reached unity. In
other words, the ASME III design curve was conservative
for constant amplitude, but non-conservative for variable
amplitude straining in environment. Critical tests to
confirm or replace this tentative observation are
recommended.
