• well going with just 1 layer of the same reinforcement gives a deflection of .35" for the spreadsheet and .07" for Mecway (changed load to .01 PSI). So the difference is much worse at 5X. There is some non linearity somewhere!

• OK TNX Victor. I'll play with a few configurations. The engineersedge is a nice site. I can run the program with 1 layer. I suspect the difference is about how the plates are fixed. I was aware of wrong thickness and that it wasnt used. The pa…

• Hi Victor....here is the laminate that you fixed with some adjusted layer property data. The stiffness of this FEA laminate is a little over twice that of a manufacturer's spread sheet using the same figures. In other words the deflection is about…

• TNX Victor! The material Gxy was off by 1000X which I fixed (should have been 410 KSI and not .41 for example). I did not bother to load the corrected one as I had bigger issues. This looks great and I can play with this. I was not setting the B…

• Here is an updated model. Not sure why the displacement min-max did not show correctly. Hopefully this one does (now min=.001,Max=1). I cannot get the failure results to work (first ply failure, safety factors). This laminate should fail at a d…

• You mean in the displacement min-max? It should be .001 -2 inches. Also not sure how to load in the Tsai-wu failure data.
