Abstract

The present paper provides C^∗-integral and COD for non-idealized through-wall cracks in cylinders under creep conditions. These solutions are based on detailed 3-dimensional Finite Element (FE) analyses which can be used for structural integrity assessment of nuclear piping. To cover a practical interest range, two types of creep conditions and two types of estimation methods were considered. Furthermore, axial through-wall crack model with internal pressure was considered. As for creep conditions, secondary creep (Norton creep), primary-secondary creep (RCC-MR creep) were considered. To estimate C^∗-integral and COD for non-idealized axial through-wall crack, GE/EPRI and ERS method were used and the results were compared with numerical solutions. Finally, an appropriate estimating methods for each creep condition were suggested.
