Abstract
The extension of a hypothetical crack in a piping elbow under fatigue loadings at elevated temperature is estimated using the analysis techniques of linear-elastic fracture mechanics. The assumptions and approximations concerning the stress and loading conditions, expected in-service operational environment, and material properly behavior that must be made in order to complete the analysis are discussed in detail.Keywords
