My thinking is bending any material, requires energy, and that generates internal heating of the material. Is it likely minor, yes, and I thought obvious, which is why my original question has more of an aero leaning, so does the "flutter" induce additional drag/turbulence/flow separation/etc or is the observed panel flutter simply the result of the above?

This question was first considered by me decades back when Nascar had roof mounted live action cameras and it was apparent the severely lightened hoods would deflect/flutter grossly at speed or when it the wake of another car, and wasn't sure if it mattered little, or they felt it was of no real consequence. It seemed the Bonneville car thread had similar issues.
