“…This is the focus of the present paper wherein; benchmark analysis has been carried out towards validation of numerical Fatigue Crack Growth (FCG) simulation. It may be highlighted that the characteristics of FCG had been investigated by many researchers in the past [3][4][5][6][7][8][9][10][11]. In the present research, two representative geometries studied in the open literature [4][5] have been selected.…”

“…The bending stress variation in the SFR piping system has a positive load ratio (R), which is defined as the ratio of the minimum stress ( min ) to maximum stress ( max ) during the cyclic load. Towards comparing the FCG behaviour of the specimen level plate-type geometry, data reported in [4] is used, and for the prototype geometric simulation, the full-scale pipe bend test data reported in [5] is used.…”

This paper describes a benchmark analysis that was performed to demonstrate numerical simulation capability on fatigue crack growth (FCG) behaviour under cyclic bending. Economic design of a piping system against the leak-before-break (LBB) criteria require an accurate estimate of crack growth behaviour. To this end, two representative geometries were selected. The first model was a plate-type geometry with a specimen-type feature, and the other model was a prototype pipe bend geometry with the component feature. The numerically simulated FCG behaviour was found to agree with published data within engineering accuracy for both the specimen-level and the component-level geometries. Details of the FCG simulation, its validation against benchmark data, and plausible reasons the difference observed in the FCG behaviour of the specimen-level and full-scale component-level geometries are presented in this paper. The results of the FCG simulation strengthen the argument for performing component-level FCG simulation for an accurate demonstration of LBB for the power plant piping systems.

In the present work, an attempt has been made to study the fatigue crack growth in a part‐through circumferentially notched pipe specimen. It has been observed that under four‐point bend cyclic load, the crack propagates in a transverse plane in the radial direction initially followed by propagation in the circumferential direction. The crack extension in the circumferential direction resulted crack growth retardation in the radial direction. This behaviour of the fatigue crack growth has been modelled, and a fatigue life prediction methodology based on an exponential model has been applied for prediction of fatigue crack growth.
