Abstract
Fracture mechanics is used for the detailed analysis of the failure of high-speed rotating cylindrical vessels. The general procedure for the analysis of fatigue life and failure used in this study is summarized; the initial material properties are also described. The results of the theoretical stress analysis are compared to the observed magnitude of the stress under the operational condition. The fracture-surface configurations observed under both optical and scanning electron microscopes are used to investigate the progress of fatigue crack propagation. Fatigue life estimates obtained by using the Paris model are compared to the actual service life of the high-speed rotating pressure vessel.
