Various objects under extreme g forces

[windy miller]

I have a friend doing an animation of 6 objects under extreme g force. Can anyone offer an opinion on how these objects would look when destroyed by extreme g forces standing on a flat indistructable surface . When will they start to change and be completely obliterated , how would it look? how much g would it take to obliterate these objects?
1. A Gummy Bear
2. An empty aluminum beverage can
3. A log of wood on its side
4. A Chrome steel sphere (3 cm diameter)
5. A diamond cube 5 cm width
6. A (hypothetical) Graphene cylinder 5cm diameter, could this last item exist?

I checked this reference

They have no entry for Gummy Bears.

Just kidding. Really, how in the world would we know the answers to those questions?

1. A Gummy Bear
2. An empty aluminum beverage can

Well, those at least you can get a good idea by stepping on them. The beverage can collapse depends on force orientation relative to the cylindrical axis.

3. A log of wood on its side

Again, stepping on some Balsa wood might give some insight. Probably dependent on grain orientation.

4. A Chrome steel sphere (3 cm diameter)
5. A diamond cube 5 cm width

Those are brittle so I would expect them to shatter, Diamonds certainly do!

6. A (hypothetical) Graphene cylinder 5cm diameter, could this last item exist?

Never played with the stuff, so I'll leave hypotheses to others.

Cheers,
Tom

p.s. you might get more ideas in the "Science Fiction and Fantasy" forum here.

completely obliterated

For the sake of discussion, what would be your criteria for "completely obliterated"?

Im going to guess it means completely unrecognisable as the object it once was.

@windy miller, You are the OP so it would seem that you are the one to determine the criteria; although, I admit that is a difficult task; and, is why I posted my inquiry after pondering the issue for a while. Based upon your above criteria, it probably depends very much upon the configuration of the original item.
An item or structure subjected to extreme gravity might leave an identifiable imprint of its horizontal configuration but leave no hint of its overall design or purpose. Heat and other factors might reduce it to a molecular level but, it doesn't appear to me that intense one uniform vertical crushing alone could achieve that.
The crushing effects of overburden gravitational crushing to even almost microscopic thinness is seen in recovered samples of deep Earth mineral strati, but the mineral and it original constituents are still identifiable.
In the case of the crushing of an item by the effects of extreme gravity on the item due to the gravitational gradient across the object's vertical dimension alone, as that gradient reduces so does the gravitational force and the required energy (m*g*h) to resist it.

A sufficiently high acceleration would result in a very high velocity. When that velocity exceeds the speed of sound in the material the structure will be lost and partial melting will take place where the object contacts the plate.

The beverage can collapse depends on force orientation relative to the cylindrical axis.

That depends on how you interpret the question. I interpreted it (perhaps incorrectly) as it being a beverage can that has been opened and emptied and left open, it which case it does not depend on orientation since everything would be pushing against a thin wall in all directions.

The OP's question is too vague.

EDIT: oh, wait ... my answer was assuming atmospheric pressure, not G force. With G force it would depend on the orientation of the application of the G force.
