A high cycle fatigue life prediction model based on continuum damage mechanics, crystal
plasticity and critical distance theory is developed. A novel damage evolution law for …

Nickel-based single-crystal alloys undergo microstructural degradation induced by thermal
exposure. The directional rafting of microstructures significantly affects the mechanical …

Circular holes in single crystal (SX) turbine blades are susceptible to creep failure at high
temperatures, due to the stress concentrations near the holes. In this study, a dislocation …

We develop the theory of homogeneous nucleation of dislocations, which predicts plasticity
incipience in FCC single crystal using material properties at elastic stage. In contrast to …

A novel continuum damage coupled unified viscoplastic model is used for simulating the
stress–strain responses of SiMo 4.06 cast iron under Low-Cycle Fatigue (LCF), fatigue …

In this study, a physics-based model is proposed to predict the γ/γ′ microstructure evolution
of single crystal (SC) superalloy at medium temperature and high stress level. Considering …

Order strengthening in nickel-based superalloys is associated with the extra stress required
for dislocations to bypass the γ′ precipitates distributed in the γ matrix. Depending on the …

In the present work, we propose a novel model coupling phase-field, dislocation density
based plasticity and damage. The dislocation density governing equations are constructed …

Turbine blades are working under complex thermal gradient mechanical loading conditions.
In the present study, a nickel-based single-crystal superalloy CMSX-4 is experimentally and …

Quantitative assessment of the initial damage state of a structure and fatigue life prediction
on this basis, especially when it is sensitive to manufacturing quality, is crucial for both …
