[NX 6] Laminate Modeler 1

[hamhamazuut]

I am trying to do FEM analysis on a composite part. However, I cannot assign my laminate to my shell model.

Anyone know of a good tutorial that guides you through a composite/laminate simulation?

Can you be more specific about your approach? And please specify your version of NX...

There are two ways (that I know of) to use the Laminate Composite Modeler in NX6.0.1 - one in which the laminate property is inherently part of the shell mesh, and another, "Global Layup", in which you create a Global Layup separate from any mesh, but assigned to contiguous Faces.

Which approach are you taking?

The Documentation has a good bit of info on the Laminate Composites Modeler.

I am using NX 6.

After I got your reply (super fast btw!), I checked out the documentation properly and you are right. It is very good on this area.

My problem now is that NX needs to much fiber/matrix material information to perform the FEA.

Any material library with standard orthotropic materials available. Like carbon, glass and kevlar fibers?

I'm not aware of any "material library" with "standard orthotropic materials". The usual caveat is that you should test the materials you plan on designing with. That said, there are a variety of resources available that describe orthotropic properties of common fiber & matrix materials. Look up Tsai, Composites Design, for instance.

Also, here is a link to a list of recommended references for composite materials design:
