A new path-dependent fatigue damage model for non-proportional multi-axial loading
Jifa Mei,Pingsha Dong +1 more
TL;DR: Wei et al. as discussed by the authors presented a new path-dependent multi-axial fatigue damage model which is formulated based on an incremental form of Moment of Load Path (MLP) on either σ - β τ stress plane or e - β e γ strain plane.

Very High Cycle Fatigue of Ni-Based Single-Crystal Superalloys at High Temperature
TL;DR: Very high cycle fatigue properties at high temperature of Ni-based single-crystal (SX) superalloys and of a directionally solidified superalloy have been investigated at 20 kHz and a temperature of 1000°C.
Journal ArticleDOI
A novel method of multiaxial fatigue life prediction based on deep learning
TL;DR: All the loading conditions mentioned above can be handled satisfactorily by the proposed deep learning-based method and excellent prediction accuracy is achieved, and the predicted lives in each study case fall almost within the scatter band of 1.5 times.

Data-driven reduced-order models for rank-ordering the high cycle fatigue performance of polycrystalline microstructures
TL;DR: In this paper, a linkage is described to connect polycrystalline microstructures to the statistically signified driving forces controlling the high cycle fatigue (HCF) responses, which is achieved through protocols that quantify these microstructure using 2-pt spatial correlations and represent them in a reduced-dimensional space using principal component analysis.

Strain-energy-density factor applied to mixed mode crack problems
TL;DR: In this paper, the authors investigated the general problem of crack extension in a combined stress field where a crack can grow in any arbitrary direction with reference to its original position, and showed that the direction of crack growth and fracture toughness for the mixed problem of Mode I and Mode II are governed by the critical value of the strain-energy-density factor.
