In the present paper, the stress-based version of such a criterion is applied to assess the results of experimental tests under HCF triaxial loading, the hollow cylindrical dog-bone specimens being subjected to a quenching heat treatment. The analytical results of fatigue life and initial crack plane orientation are compared with the experimental data. © 2020 The Authors. Published by Elsevier B.V.

Several structures are subjected to multiaxial cyclic loading (Refs by Hu et al., 2019, and Xue et al., 2020) and, due to the complexity of performing multiaxial testing, different criteria to estimate fatigue life of such structures have been proposed (Refs by Fatemi and Shamsaei, 2011, de Freitas, 2017, Chmelko and Margetin, 2020). t t l it i lti i l t ti , i t it i t ti t ti li t t t i i, , it , , l ti , .
