Abstract
The paper describes experimental results of multiaxial tests on AM AlSi10Mg cavity specimens with the special focus on the phase shift effect. 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.
