When my team first made this flex plate, the purpose was to make one that doesn't crack due to torque, not flexibility, so we ran the analysis and avoid having holes at the area where it has lower strength. We added the thickness to the center portion and left the outer part the same, and this is to avoid adding flex strength either. For the material we followed the SFI regulation for the gasoline engine, not the diesel engine one, so the flexibility is within requirement. We also ran a simulation as well as a dynamic balance with the torque convertor on at 12000rpm for an hour, just to ensure everything works and not going to crack in real life.
