  I am trying to simulate a uniaxial static compression test of sandwich structure. To capture its non-linear behavior I need to know the 'Tangent modulus' of aluminum alloy 6060 (AA 6060). Can anyone help me providing this data?

  You can run the model with a Tangent modulus of 0 while you are looking for a better value. This will create a lower bound on the forces developed during the static compression test simulation.

  Thanks for your reply.
  Will it be a conservative design (for my sandwich structure) when using a tangent modulus of 0?
  Actually, what is the physical significance of the tangent modulus of 0? If clarifying a bit further would be very helpful for me.
