Book Description
The effects of compressive loads on structural fatigue at elevated temperatures are investigated using plain, notched, and welded Titanium 8Al-1Mo-1V, and PH 15-7Mo stainless steel coupon specimens. Specimens are subjected to Mach 3 spectrum test environment, including compressive loads. Fatigue life predictions are compared with spectrum teset results. The influence of prior stress-strain history on subsequent life is considered. Prediction methods are extended to include the compression range, and results notched specimens is determined analytically and experimentally. A variety of individual variable fatigue tests are performed at temperatures up to 900F.
