[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,

I am using ABAQUS Software for analysis of laminated composite plates (279X279X2.16) and (0/90)4s having 16 plies; trying to perform Buckling and Post buckling analysis using Static Rikโ€™s algorithm.

Firstly, Eigen value analysis is performed in step one, and thus bulking load is predicated.Then Eigen values are incorporated in Static Rikโ€™s Non-linear analysis for imperfection (1% of first Eigen mode,0.05% of second Eigen mode, 0.025% of third mode and 0.025% of forth mode)using edit keywords method.
