Finite Element Simulation of Deep Drawing of Aluminium Alloy Sheets

Abstract

More and more automobile companies are going for weight reduction of their vehicles for fuel economy and pollution control. At elevated temperatures aluminum sheet alloys 6061 and 7075, the blank temperature effect on forming behavior and damage factor of these sheets is the objective of the present study. In automotive parts the aluminum alloys have good corrosion resistance, high strength to weight ratio and low formability of aluminum sheets limits in some products with complex shapes. The elevated forming process is intended to overcome this problem. An insight into such a study will throw light on the different temperatures required by the above materials when they are made into TWBs. Using ANSYS a series of simulations were carried out in the present investigation on the formability behaviour of deep drawing of aluminium alloys in the temperature range 200-500°C.
