Predicting earing in metal sheet forming simulation

      Hi,

      I am trying to predict the earing profile in a cup drawing simulation from this benchmark problem:

      Martin Watson et al 2016, Failure Prediction after Cup Drawing, Reverse Redrawing and Expansion.

      I have tried material models MAT36 and MAT133 but I could not capture the earing profile.

      Would you suggest a particular material model to capture this phenomenon ?

      Many thanks

      Please explain what an earing profile looks like. I don't think many readers know what you are talking about.

      the earing profile should look something like this after the drawing process is finished.
