Four typical representatives of multiaxial fatigue strength criteria are assessed to check the correlation of their results with fatigue experiments. The use of the QCP and Liu-Zenner criteria provide overall better results than the Dang Van criterion and the Crosland criterion, but none of the four evaluated criteria fits well to both checked multiaxial loading configurations. The potential reasons for the found discrepancies are commented in the discussion section. © 2023 The Authors. Published by ELSEVIER B.V.

Introduction The number of multiaxial fatigue experiments on AM metallic specimens in the high-cycle fatigue (HCF) domain remains limited at this moment, see, e.g., the survey by Foti et al. (2023). Even in the case of subtractive manufactured metals, some questions on the common behavior in the multiaxial configurations stay open, and it is hard to find a Fatigue Design 2023 (FatDes 2023) Multiaxial fatigue analysis of additively manufactured hollow specimens from AlSi10Mg Jan Papuga a, *, Luís Reis b , Martin Matušů a , Pedro R. da Costa b , Jan Šimota a , Jakub Rosenthal c , Francisco Bumba b a Faculty of Mechanical Engineering, Czech Technical University in Prague, Technická 4, 166 07 Prague 6, Czechia b IDMEC, Instituto Superior Técnico, Universidade de Lisboa, Av.
