Multiaxial fatigue of aluminium friction stir welded joints: preliminary results
The aim of the present research is to check the accuracy of the Modified Wöhler Curve Method (MWCM) in estimating the fatigue strength of friction stir (FS) welded tubular joints of Al 6082-T6 subjected to in-phase and out-of-phase multiaxial fatigue loading. The welded samples being investigated...

| description | The aim of the present research is to check the accuracy of the Modified Wöhler Curve Method
(MWCM) in estimating the fatigue strength of friction stir (FS) welded tubular joints of Al 6082-T6 subjected to
in-phase and out-of-phase multiaxial fatigue loading. The welded samples being investigated were manufactured
by equipping an MTS I-STIR process development system with a retracting tool that was specifically designed
and optimised for this purpose. These specimens were tested under proportional and non-proportional tension
and torsion, the effect of non-zero mean stresses being also investigated. The validation exercise carried out by
using the generated experimental results allowed us to prove that the MWCM (applied in terms of nominal
stresses) is highly accurate in predicting the fatigue strength of the tested FS welded joints, its usage resulting in
estimates falling with the uniaxial and torsional calibration scatter bands. |
