A simple question for starters. For the purpose of a full scale mock-up, what thickness plywood best mimic's an infused panel's capacity to be tortured?
What minimum radius in an infused panel can a hand tortured curve be bent?
Too many variables. Torturing is a function of the materials ability to stretch/compress. Foam stretches a lot, ply a little, glass not at all. Stiffness is a linear function of the surface material (glass is stiffer than wood) but a cube function of stiffness. If you want to torture a composite panel, it is easiest if you leave the glass off one or both sides until it is bent.
An example of the bend at it's most tortured is the quarter panels on the leeward side of the windward hull in the animations in the Folder called Flat Wrapped Hulls.
Thanks in advance.
