Salome meca for composite

Dear Forum

Before to post a tutorial for composite modeling on the wiki, I'm doing some test case to validate my .comm file

I'm in trouble with CRIT_ELNO_RUPT results from aster using salome meca 2009 --> more information at:

www.code-aster.org/forum2/viewtopic.php?id=13177

Did somebody checked aster results in ply coordinate system for ply orientation other than 0 or 90° (used in validation case ssls128a)
and EL not egal to ET

thanks in advance

I have posted more comparison between CLT software and code ASTER for composite analysis on code aster forum.

I still have some issues calculating stresses in ply coordinate system.

I mean I know how to extract those results but they are not in line with the analytical solution

I would like to know if someone did validate/used this function before (CRIT_ELNO_RUPT)?

I would be really interested to look at a command file that works with plies at 45° to find my mistake

thanks in advance

Nobody interested in composite analysis ?

Thanks for your feedback

At this step, I'm now trying to check how SIGT,SIGL and SIGLT are calculated by ASTER in the source code

Angle definitions are looking to be consistent with the CLT analysis but I found something strange in the way to transfert stresses from laminte CS to ply CS

More details on Code ASTER forum

hope this will be clarified soon

I have upload on code aster forum modified fortran files that gives good results (to my opinion) when used as &quot;surcharge&quot; in code aster

Any test cases or feedback from other users will be appreciated a lot
