Validation test of a predictor of fatigue failure under biaxial out-of-phase loading conditions

The definition of a new predictor of failure initiation in high-cycle fatigue, previously calibrated for aluminum alloys on the basis of uniaxial experimental data and tested against biaxial in-phase data, was modified to account for biaxial out-of-phase loading. The process of validation, with reference to the results of three biaxial out-of-phase fatigue tests, is described. (c) 2021 Elsevier B.V. All rights reserved.

Automated summary

The study focused on improving the prediction of high-cycle fatigue failure initiation by modifying the predictor to account for biaxial out-of-phase loading, and validated the new model through three biaxial out-of-phase fatigue tests.
