Dear
Thank you again.

I promise this will be my last question in this thread. The query is a little generalized.

As you know in the 2D model the prestress applied is two-directional (x and y-direction). But I don't understand why the stress gradient we get is like this irrespective of 2D plane stress, 2D axisymmetric, 3D.

S11 (Normal stress in the x-direction)



S22 (Normal stress in the y-direction)



Actually, I am showing here the Abaqus model just because I have this bowtie effect plotted in ABAQUS. I did the same thing in ANSYS also, the result is the same.

Why this bowtie effect is occurring, can you please let me know if it is possible? I will be grateful.

Thank you very much.

Regards
