From the plots you show the strains are well below the .2% thus the parts are in a linear range.
Did you notice the pop rivet on the plastic laminate?
Again great results and thanks for sharing David. Like I said before lost of memory and gray hair are on the same path one losses color and the other I not sure what!!!!!

Thanks Hish,

One final takeaway from all of this is that the stainless steel (SS) panel is stiffer than the FRP used on the H3; the critical buckling loads are about the same but the SS panel deflects half of the FRP amount. This means there's more stress on the glue with the SS panel. If we assume the tubular spaceframe wall has the same stiffness as an FRP panel, then the FRP panel and the wall share the loads equally. Given that the SS panel is around twice as stiff as the FRP panel, in this same scenario the SS panel will support 2/3rds of the loads and the wall 1/3rd. Stresses in the glue get the same treatment. The stresses in the SS adhesive would be 33% greater than in the FRP adhesive.
