Hi Jack, if you know the nodal stress values, you can interpolate them at 4 integration points (IP) with zai and eta value of 1st IP (zai=-0.577, -0.577), 2nd IP (zai=0.577, -0.577), 3rd IP (zai=0.577, 0.577) and 4th IP (zai=-0.577, 0.577) for the linear element formulation in this video. Here 0.577=1/sqrt(3) are local coordinates of Gauss IP.

This is a really nice work. Thanks a lot. Could you please add a lesson about how to intepolate the stress at the integration points not the nodes?

@@10MinutersOk. I got it. Thanks a lot for your answer.
thanks for this video. can you share me coding related to uhyper subroutine.?
Hi,
Not sure if it helps, but here is a repository sharing UHYPER subroutine:
