The interaction of creep and fatigue for a rotor steel
TLDR
In this article, 20 tests were performed on a 1 Cr−1 Mo−1/4 V rotor steel at 1000° F (538°C) to determine the interaction of creep and low-cycle fatigue.Abstract:
Twenty tests were performed on a 1 Cr−1 Mo−1/4 V rotor steel at 1000° F (538°C) to determine the interaction of creep and low-cycle fatigue. These tests involved five different types of strain-controlled cycling: creep at constant tensile stress; linearly varying strain at different frequencies; and hold periods at maximum compressive strain, maximum tensile strain, or both.read more

A damage function and associated failure equations for predicting hold time and frequency effects in elevated temperature, low cycle fatigue
TL;DR: In this article, a new approach was developed for predicting strain-controlled, low cycle fatigue life at elevated temperature using a proposed energy measure of fatigue damage, defined as the net tensile hysteretic energy of the fatigue cycle, can be approximated by the damage function σTΔep, where σ T is the maximum stress in the cycle and Δep is the inelastic strain range.

Energy criterion for high temperature low cycle fatigue failure
TL;DR: In this paper, high temperature total endurance tests were conducted on three alloys (316L steel at 550°C, 9Cr-1Mo steel and Nimonic 101 at 850°C) in low cycle fatigue under continuous cycling.

TL;DR: In this article, the use of the scanning infrared camera for monitoring traveling cracks and mapping the temperature fields resulting from stress concentrations in cyclically loaded materials is also demonstrated, and the results indicate that this instrument is of value in both nondestructive testing and crack propagation studies.

Creep-fatigue analysis by strain-range partitioning.
TL;DR: Strain-range partitioning as discussed by the authors provides unifying framework for characterizing high-temperature, low-cycle, creep-fatigue properties of metals and alloys and offers distinct advantage to designers of immediately providing reliable upper and lower bounds on cyclic life for any type of inelastic strain cycle that may be encountered in service.
