Experimental and Numerical Assessment of Thermal Fatigue Damage for 316L and P91 Components at Elevated Temperature
This paper presents thermal fatigue tests and analysis of thick-walled pipes of 316L and P91 steels at 550°C with different levels of axial load. The evolution of the cracking is measured with X-ray tomography and time-of-flight diffraction. The fatigue life modelling is based on a thermal analysis and elastic-plastic stress analysis plasticity corrected stress intensity factors. Considering the complexity of the loading and crack development the applied engineering model predicts the observed fatigue life quite well.
