Hi Fabricio,

  It's possible, but more importantly, the metal plasticity material models are anticipating a true stress-strain data. So when you input Engineering stress-strain data you are getting a wrong result.

  Some suggestions:

  • Keep an eye on the plastic strain in your simulation is it may be exceeding the max. value you might have provided.

  • Remove the initial points in your simulation (0 & 0.0001) and just start from 0.02 plastic strain and see if it helps.

  • Increase the maximum sub-steps to about 1000.
