so you specified a different youngs modulus? The yield curve only
becomes relevant after the initial yield stress is reached, before
that material is linearly elastic.

For example, I give a linearly increasing yield curve with slope of 100, and then I give a yield curve with slope of 100.1 I get the same force in the first few increments during the calculation. I tried using double precision and also fully integrated elements.
