Fatigue at Elevated Temperatures: A Review of Test Methods

Abstract

The study of fatigue at elevated temperature requires the evaluation of material response to several load-time profiles in specified thermal-chemical-nuclear-electric fields. This review of test methods emphasizes the relationships between “pure low-cycle fatigue” and tensile, fracture toughness, creep, cyclic-creep, creep fatigue (interspersion), fatigue-cycle-with-hold, dynamic creep, fatigue crack growth, and high-cycle fatigue testing. The thermal and environmental control is discussed. Special attention is given to isothermal-uniaxial, bending, torsion, and combined stress tests. Cyclic thermal testing is reviewed. Strain measurement, signal conditioning, computer utilization, fatigue crack growth, vacuum and environmental control, nondestructive testing, acoustic emission, and fractography are reviewed as they pertain to fatigue at elevated temperature. Specimen design, gripping, and testing machine characteristics are also discussed.

High‐temperature creep‐fatigue‐oxidation behaviors of P92 steel: Evaluation of life prediction models

“…Models based on Manson–Coffin equation include frequency‐modified (FM) 39 and frequency‐modified damage function (FM‐DF) 38 models. Notably, the Manson–Coffin equation has been widely used to determine the fatigue life, which describes the relationship between and 40 .…”

Data Processing Package for Cyclic Integrated Reversible Bending Fatigue Testing

“…Bending fatigue testing has been practiced for some time. [3][4][5][6] According to the beam boundary condition, the testing can be classified as cantilever beam flexure, 7 three-point bending, four-point bending, [8][9][10][11] and pure bending. 12 Bending fatigue tests also include variants that have been developed in response to environmental factors, particularly temperature.…”

Effect of temperature on high‐cycle fatigue and very high cycle fatigue behaviours of a low‐strength Cr–Ni–Mo–V steel welded joint

“…Fatigue behaviour of engineering materials at elevated temperatures has long been a focus since the early 1970 s. Many works have been reported on low‐cycle fatigue and high‐cycle fatigue (HCF) behaviours by attaching great significance to fundamental deformation and damage mechanisms, environmental/oxidation effects and interactions between environment and deformation mode at higher temperatures.…”
