The Effect of LWR Coolant Environments on the Fatigue Life of Reactor Materials
Omesh K. Chopra,W. J. Shack +1 more
TL;DR: In this paper, the effects of key material, loading, and environmental parameters, such as steel type, strain amplitude, strain rate, temperature, dissolved oxygen level in water, flow rate, surface finish, and heat-to-heat variation, on the fatigue lives of these steels are summarized.
Journal ArticleDOI
A review of irradiation effects on LWR core internal materials – IASCC susceptibility and crack growth rates of austenitic stainless steels
Omesh K. Chopra,A. S. Rao +1 more
TL;DR: In this paper, the effects of key parameters such as material composition, irradiation dose, and water chemistry on IASCC susceptibility and crack growth rates of Austenitic stainless steels in light water reactor (LWR) environments were evaluated.
Journal ArticleDOI
Using artificial neural networks to predict the fatigue life of carbon and low-alloy steels
T.Todd Pleune,Omesh K. Chopra +1 more
TL;DR: In this paper, a data base of 1036 fatigue tests was used to train an artificial neural network (ANN) to predict fatigue life for specified sets of loading and environmental conditions.
Journal ArticleDOI
