Finite elements analysis is commonly used in the cans tool design since it allows predicting different sheet metal defects and instabilities that significantly affect the efficient production of beverage cans. These defects include earing, due to the material orthotropic behavior, thinning and fracture, which result from different combinations of strain paths. The process conditions considered in this work are the ones established for the BENCHMARK 1 – Failure Prediction after Cup Drawing, Reverse Redrawing and Expansion, proposed under the NUMISHEET 2016 international conference. The two materials under analysis are an AA5352 aluminum alloy and a TH330 steel, whose orthotropic plastic behavior is modelled with the CB2001 yield criterion. The anisotropy parameters are identified considering different weights for the set of experimental data available, allowing to analyze the impact of small changes in the yield surface on failure prediction. All numerical simulations are performed with the in-house finite element code DD3IMP.
