  I hope you are talking about "strain energy" which is equal to 1/2*stress*strain * volume (for an axial bar under compression) . Steel is much stiffer than aluminum, so for the same displacement it should ideally absorb higher energy than aluminium. Could you make sure that the material properties inserted are correct? It would help if you can share images describing the model setup.
  Regards Ishan.

  No, I am talking about Stiffness energy (photo).
  Can You help to explain this difference?

  That is a tracker (stiffness energy) that is fairly new and is not a contour or post processed result - it just tracks the model energy during the solution.
  Thus use a strain energy result plots for post processing results.
  The stiffness energy is the same as the total strain energy as can be seen below where the stiffness energy and the total strain energy of the model are the same.

  Thank You. I will try get strain energy plot.

  not me either :) - just saw it for the first time - never used it before.
