Description
Summary:Aluminum alloys are widely used in manufacturing of aircrafts and in automotive industry. In this paper aluminum alloy 5052 of 0.5 mm thickness was utilized to investigate deformation behavior in stretch flanging process. The effect of process parameters such as initial flange length, punch-die clearance and blank-holding force were investigated using FE simulation and experimentation. The results show that the circumferential strain and radial strain increases with increase in initial flange length and blank-holding force and decreases with increase in punch-die clearance. Experimental investigations were also carried out to validate FE simulation results. A very good agreement was obtained between FE simulation results and experimental in terms of punch load and edge crack location and propagation.
