A comparison of Ansys Shell181 and Solsh190 elements

Please find attached a report on a comparison between ANSYS SHELL181 and SOLSH190 elements with particular emphasis on applicability to linear elastic sandwich panels.

Title: Comparison of Ansys elements Shell181 and Solsh190

Abstract:

[ANSYS] Composites. Problems using shell181 at postproc and tsai-hill criterion

Hi all,

I've modeled a composite sandwitch with ANSYS with a pressure. The element chosen was SHELL181.
I want to know the Stresses in the x, y and xy directions; the displacements and the deformations only in a few points so as to compare with the Navier and Rayleigh-Ritz solutions made following Reddy's book.

1.-The first problem is that I don't know how to ask ANSYS to list the displacements and deformations.

2.-The second one is that I know how to ask ANSYS to list all the elements in a layer,
