Monitoring Low-Cycle Fatigue Material-Degradation by Ultrasonic Methods [PDF]
, 2010 Any system consisting of structural material often undergoes fatigue, which is caused by dynamic load cycle. As a structural system, nuclear power plant is very likely to have low-cycle fatigue at many of its components.

An Investigation of High-Cycle Fatigue Models for Metallic Structures Exhibiting Snap-Through Response [PDF]
, 2008 A study is undertaken to develop a methodology for determining the suitability of various high-cycle fatigue models for metallic structures subjected to combined thermal-acoustic loadings. Two features of this problem differentiate it from the fatigue of

Effect of Loading Frequency on the Fatigue Response of Adhesive Joints up to the VHCF Range
Applied Sciences, 2023 Modern structures are designed to withstand in-service loads over a broad frequency spectrum. Nonetheless, mechanical properties in numerical codes are assumed to be frequency-independent to simplify calculations or due to a lack of experimental data ...

Asymptotic residual stresses in butt-welded joints under fatigue loading [PDF]
, 2016 If a weld toe is modelled as a sharp V-notch angle, the stress distribution near the notch tip is singular. Its intensity can then be quantified by means of Notch Stress Intensity Factors (NSIF), which have been proven to be capable of summarising the ...

The influential factors on very high cycle fatigue testing results
MATEC Web of Conferences, 2018 When the fatigue cycle is extended from high cycle (105~107) to very high cycle (107~109), the fatigue testing results will be more sensitive to the influential factors such as specimen size, specimen surface roughness and the inclusion size.
