Heat and weight. Put it in the driveway. Lay it across two 2 x 4's curve up. Set some HEAVY stuff in the middle and let it set for an hour or so. When it flat use some c-clamps and 2x4's to clamp across it to keep it flat. Do the next piece and then clamp it to the other. No Guarantees.

building the ice shanty this winter, much of the green treat plywood warped as it dried leaning up against the wall of the garage. we tossed the pieces in the lake for about 20 minutes, then put them on the heated floor curve up and stacked a bunch of weight on the pieces. while they were not perfect, they did straighten out fairly well. as a last resort, try adding moisture, then forcing flat and allowing to dry.
