Thank you for detailed answer, this is main structural element in transversal direction. Regarding your proposals, my sketch is oversimplified, it...
Hi guys, I am in doubt how to tackle this situation. I have relatively deep V hull and requirement is to have top of the floor/stiffener in line...
I agree with you, I get same low numbers for Wmin; aprox 6 times lower dry fiber weight per panel than calculated through ply by ply method. I...

It is me again :D With every day I am closer to the finish line; I have successfully calculated all structural elements except bottom stiffeners,...
Thank you, now the story regarding composite Young`s modulus is complete, progress is slow but it is exists :)

Thank you once again for support in this battle :D
Hi guys, Just to confirm, it is first time that I`ve encountered this way of formula writing; page 20. At first picture, I have to choose maximum...
@TANSL haha, thanks. I have also 2008 rules, and I agree with you, also I´ve read other posts on this subject so I am aware that quality is low...
