Hello ~ Does anyone have a snap shot or a document you could refer me to for understanding how Nastran is computing the output vector "6066 - Laminate Min Strength Ratio" for a 2D orthotropic laminate?
Best,

I was just curious if anyone had already built and is will to share their spread-sheets for digesting raw test data executed under a specific ASTM #?

Hi Blas,
I apologies not getting back to you sooner, always many fires to put out. This is some great feedback, and I had a strong gut feeling telling me this was the incorrect solver to be using for these contact nonlinear high strain / displacements FEM models. Unfortunately we do not have...
Hi Blas Molero,
I appreciate your feed-back, I uploaded the results file... Anyways it seems to be a repeated problem with multiple models I've created. I'm going to try a few different approaches this week to minimize the contact elements.

Yes I did, I ran SOL101 and SOL103, reviewed the model and everything seems to be in working order. I think the problem is the isotropic boss stiffness relative to the shell elements, the all-composite liner puts a larger bending stress at the boss root, and I think the model is having a hard...
Hello Everyone,
I've read thru some great responses regarding troubleshooting negative diagonal ratios & excessively large MAXRATIO, I was hoping we could take a look at my current f06 output and get some constructive feedback.
The general model:
1.) All composite pressure vessel
2.) Liner is...
