I'm unsure about the exact term for this process, but it is commonly used in various animations

Insider Blender Object

I have an object and I want to animate its internal components, similar to the example shown above. I attempted to split the object and rotate one part by 180 degrees, but it didn't achieve the desired result as seen in this animation. I believe there must be a standard method for accomplishing this. I would greatly appreciate any assistance or suggestions for tutorials on this topic.

you can achieve this effect pretty easy with geometry nodes:

using this node tree:

you get this:

arc animation filled + extruded:

and then just boolean mesh that with your object.

Of course you have to take care that this animated cylinder is bigger than your object and "hides" your object.
