Hi everyone!
I have to make a confrontation with Abaqus, which made a structural analysis of an anisotropic plate, and in order to do that, I need the lamination matrices A,B,D,Ashear computed by it. Can someone tell me how to obtain them?

Thank you in advance.

Check this thread, it explains how to view/manipulate those matrices:

@FEA way
The DS knowledge Base for answer QA00000008126 doesn't seem to be available. I went to 'Simuleon by Technia' site and found a blog in which they talked about a plugin called 'Abaqus material and section definition copyer'. Is that the plugin I need?

@FEA way
I have tried to use the following line in the Abqus routine, but I don't see differences.
*ELEMENT MATRIX OUTPUT, ELSET=Plate, OUTPUT FILE=RESULTS FILE.
(Plate is the name of the interested set)

There are some occasional issues with availability of Knowledge Base but it might be also related to access restrictions (at least some of the articles are for customers only). The article still exists and is titled "Abaqus/CAE plug-in to calculate A, B, and D matrices and equivalent extension and bending moduli for composite lay-ups" and the name of the plug-in is "Calculate ABD Matrix".

Did you check the results file (.fil) ? That's where Abaqus saves the requested matrix output in this case.
