[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,

First ply failure of composite panels using ABAQUS

Choose a channel featured in the header of iMechanica: 

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 Rik’s algorithm.

Firstly, Eigen value analysis is performed in step one, and thus bulking load is predicated.Then Eigen values are incorporated in Static Rik’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.
