Abstract: The major problems associated with forming operations of metal sheets are edge failures often associated with the stretch flangeability of the material. Several ferrous and non-ferrous metals and their alloys have been studied in the recent decade to address the above mentioned issue. Stretch flangeability of a materials used in automotive applications is determined by several tests, the prominent ones being hole expansion test and uniaxial tensile test along with bending tests. The stretch flangeability of AA6016 was studied by finite element method hole expansion test. It is developed on ABAQUS/CAE 2020with implicit simulation. A finite element model is developed with appropriate material model for understanding the significance of physical parameters affecting the stretch flangeability. Simulation results provide a greater access to analyse mechanical properties acting under deformation.
