title = "Thermal fatigue of NPP components: potential multiaxial, environmental and small cycle effects",
abstract = "Current fatigue design curves for NPP components are based largely on strain controlled tests of small specimens tested in air at room temperature. Reduction factors of 2 for strain or 20 for fatigue life are applied to the mean data and are intended to account for material, environment, surface finish and loading uncertainties. Pipe failures in recent years have been attributed to high cycle thermomechanical fatigue and have prompted re-evaluation of the fatigue design curves. Research has focussed especially on environmental effects and load sources. Some data also suggests that multiaxial loading and small stress cycles as part of a spectrum may cause significantly more fatigue damage than what is predicted. This paper examines some of these potential sources of fatigue damage.",
