Structural Foam for chassis stiffening

wow,,,,,I'll try to be less verbose.

I've spent weeks being trained in using FEA and CFD software and use it regularly. I'm well aware of the caveats. All tests started with FEA but I believe at least 2 of them validated their model with bodies in white.

The mazda beam was tested such that increased "adhesion strength" in the shear plane improved performance. This was because they were mostly focusing on improving crash performance. While I agree that it's a significant factor, I'm not so sure a benefit can't be had without the perfect bonding surface.


Have a little more open mind,,,,containing the foam to a finite area is as simple as a child's balloon:

Measuring torsional rigidity is not over complicated. A simple Before/After comparison is more than most vendors provide. Was USCT simplistic "look at the tape sag" equally scrutinized?
