| Popis: | The following investigation provides knowledge about the fatigue behaviour of welded wrought magnesium alloy AZ31 (ISO-MgAl3Zn1). Three different types of joints, fully penetrated and partially penetrated butt welds, transversal stiffeners, were tested under fully reversed (R = -1), pulsating (R = 0) and high mean tensile (R = 0.5) loadings. The results were presented according to the nominal, structural (hot-spot) and notch stress (rf = 1.0 and 0.05 mm) concepts. For these four concepts the FAT - values according to IIW- Recommendations were derived and compared with those already known for welded steel and aluminium joints. |
