Hi,

I think you can calculate the values from the above two diagrams and  check how much difference you see between the two values. Choose the value based on your requirement. For example a higher tangent modulus might give lower deformation but a higher stress and lower tangent modulus will give a lower stress after yielding but higher deformation. If your concern is plastic deformation then go with lower values of tangent modulus.
