Thermographic detection of fatigue damage of pressure vessel steels at 1,000 Hz and 20 Hz

A thermographic infrared detection system has been used to measure the temperature profiles during fatigue testing of specimens of reactor pressure vessel steels at 1000 Hz and 20 Hz. Four stages of temperature profiles were observed during fatigue testing: an initial increase of the average specime...
