stubborn brake drum removal on 2002 Hyundai Elantra

When first attempts fail, how can the drum be removed from the rear wheel on an Elantra.

May just be rusted/seized to center hub and just needs to be rattled with taps from hammer. Can tap on outer edges of drum to break loose with hammer vibes but recommended is to tap at the center area and vibe loose to allow removal. Careful not to hit stud threads and don't get ridiculous with how hard you hit or size of
