Physical-Mechanism Exploration of the Low-Cycle Unified Creep-Fatigue Formulation
Metals, 2017 Background—Creep-fatigue behavior is identified as the incorporated effects of fatigue and creep. One class of constitutive-based models attempts to evaluate creep and fatigue separately, but the interaction of fatigue and creep is neglected.

An Explicit Creep-Fatigue Model for Engineering Design Purposes
Metals, 2018 Background: Creep-fatigue phenomena are complex and difficult to model in ways that are useful from an engineering design perspective. Existing empirical-based models can be difficult to apply in practice, have poor accuracy, and lack economy.
