Abstract

Due to the complexity of loads and structures, as well as the uncertainty of transverse crystal orientation, accurately predicting thermomechanical fatigue (TMF) damage in nickel-based single crystal turbine blades remains a challenge. In this paper, a slip-based damage model reflecting the coupling of creep damage and low-cycle fatigue damage was employed to describe the in-phase thermomechanical fatigue (IP TMF) damage behavior of nickel-based single crystal turbine blades. The lifetime prediction results of creep, low-cycle fatigue, and IP TMF based on this model were essentially within a 2x scatter band. Then, the damage model was integrated into the slip-based Walker constitutive model, and the finite element implementation of the improved damage-coupled crystallographic constitutive model was performed using the secondary development tool (User Programmable Features, UPFs) provided by ANSYS. Furthermore, considering the influence of the randomness of transverse crystal orientation, the IP TMF damage of nickel-based single crystal turbine blade was simulated, and the predicted dangerous zone was consistent with the crack initiation zone observed in previous IP TMF experiments.

期刊介绍： Typical subjects discussed in International Journal of Fatigue address: Novel fatigue testing and characterization methods (new kinds of fatigue tests, critical evaluation of existing methods, in situ measurement of fatigue degradation, non-contact field measurements) Multiaxial fatigue and complex loading effects of materials and structures, exploring state-of-the-art concepts in degradation under cyclic loading Fatigue in the very high cycle regime, including failure mode transitions from surface to subsurface, effects of surface treatment, processing, and loading conditions Modeling (including degradation processes and related driving forces, multiscale/multi-resolution methods, computational hierarchical and concurrent methods for coupled component and material responses, novel methods for notch root analysis, fracture mechanics, damage mechanics, crack growth kinetics, life prediction and durability, and prediction of stochastic fatigue behavior reflecting microstructure and service conditions) Models for early stages of fatigue crack formation and growth that explicitly consider microstructure and relevant materials science aspects Understanding the influence or manufacturing and processing route on fatigue degradation, and embedding this understanding in more predictive schemes for mitigation and design against fatigue Prognosis and damage state awareness (including sensors, monitoring, methodology, interactive control, accelerated methods, data interpretation) Applications of technologies associated with fatigue and their implications for structural integrity and reliability. This includes issues related to design, operation and maintenance, i.e., life cycle engineering Smart materials and structures that can sense and mitigate fatigue degradation Fatigue of devices and structures at small scales, including effects of process route and surfaces/interfaces.
