Advances on creep–fatigue damage assessment in notched components [PDF]
, 2017 In this paper, the extended Direct Steady Cyclic Analysis method (eDSCA) within the Linear Matching Method Framework (LMMF) is combined with the Stress Modified Ductility Exhaustion method and the modified Cavity Growth Factor (CGF) for the first time ...

Studies of High-Temperature Fatigue Behavior and Mechanism for Nickel-Based Superalloy Inconel 625
Metals, 2022 Strain-controlled continuous fatigue and creep–fatigue tests were carried out at 700 °C and 800 °C on Inconel 625 alloy. The effects of strain rate and tensile-hold time on cyclic stress response and fatigue life were investigated.

Muscle Activity Adaptations to Spinal Tissue Creep in the Presence of Muscle Fatigue. [PDF]
PLoS ONE, 2016 The aim of this study was to identify adaptations in muscle activity distribution to spinal tissue creep in presence of muscle fatigue.Twenty-three healthy participants performed a fatigue task before and after 30 minutes of passive spinal tissue ...

Modeling of creep-fatigue interaction effects on crack growth at elevated temperatures
MATEC Web of Conferences, 2018 The well-known load frequency effect on creep-fatigue crack growth is explained by the interactions between fatigue and creep loading and is quantified using the concept of plasticity-induced crack closure.

Creep and creep–fatigue crack growth [PDF]
International Journal of Fracture, 2015 Creep and creep–fatigue considerations are important in predicting the remaining life and safe inspection intervals as part of maintenance programs for components operating in harsh, high temperature environments. Time-dependent deformation associated with creep alters the crack tip stress fields established as part of initial loading which must be ...
