In tensile testing of FSW joints of Mg alloys, the stress-strain curve wasn't linear. Could you clarify to me the reasons behind this?
One reason could be due to some movements of the machine itself, which means filling the gap in contact surfaces.
Slipping of the grips
If you are using inappropriate grips shape & type for the workpiece, then the friction between the surfaces of the grips and the workpiece will be weak and cause the workpiece to slip during the testing process causing inaccurate data collection.
