In this work, cold bulge forming of an Aluminium-Magnesium (Al-Mg) sheet with a solid bulging medium is performed experimentally and numerically.  Mechanical properties and thickness variations of Al-Mg sheet are evaluated before and after the forming process.  The results indicated that the Al-Mg sheet has taken the desired shape without necking using the cold bulge forming process.  Also, the...

In this study, property criteria for automotive Al-Mg-Si sheet alloys are outlined and investigated in the context of commercial alloys AA6016, AA6005A, AA6063 and AA6013. The parameters crucial to predicting forming behavior were determined by tensile tests, bending tests, cross-die tests, hole-expansion tests and forming limit curve analysis in the pre-aged temper after various storage period...
