A Creep Constitutive Model, Based on Deformation Mechanisms and Its Application to Creep Crack Growth

Metals, 2022
In this paper, a constitutive model, based on the creep deformation mechanism in P91 steel, under a wide range of stress levels, was established and embedded into finite element software.

Crack Propagation Mechanisms for Creep Fatigue: A Consolidated Explanation of Fundamental Behaviours from Initiation to Failure

Metals, 2018
Background—Creep-fatigue damage is generally identified as the combined effect of fatigue and creep. This behaviour is macroscopically described by crack growth, wherein fatigue and creep follow different principles.

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.
