Reply To: Why does the structure not affect the results in a tensile test?

You have plasticity in the model. Bilinear Isotropic Hardening is one type of plasticity.
Try using 0 for the Tangent Modulus.
Another issue with your model is the number of elements through the thickness of the wall. Please show a close-up image of the mesh that shows how many elements are across the thickness.
