Paper Title:
Prediction of Fracture in Square-Cup Forming of Aluminium Alloy
  Abstract

Aluminum alloy sheet is becoming one of the main materials to take the place of steel components to reduce the vehicle mass due to the advantage of low special density, high strength and corrosion resistance. To predict the formability during the aluminium alloy sheet forming accurately, , a ductile fracture criterion developed by the authors, was for numerical simulation, in this paper. Fracture behavior in square-cup forming of the aluminium alloy LF21M was predicted by means of the criterion. Comparison of the predicted results with experimental values shows that the critical punch stroke and the fracture initiation position in square-cup forming of the aluminium alloy have been predicted successfully by the criterion.
