I mean so far in my opinion it's just one assumption to another assumption, although I'll wait for Ugarik's explanation on toughness.

Well making every calculation requiring a material science university bachelor degree is nice in theory but a big no in practice - like this is a literature review on fictional characters fighting after all - hell this site is for indexing characters' fighting prowess with the same set of standards in the first place.Cropfist said:

Here we have a 0.2 m^3 concrete block with thoughness of 0.5 J/cm^3. Compressive strength of that block is 10 MPa and it's ductility is 10% (meaning it can loose 10% of its original length without fracturing)
And we also have a metal ball with KE of 100,000 J. Everything else we can see from the picture. Stress-Strain Curve is at the bottom-left.

Now you can crearly see that if we increase the volume of the block by 2 time the ammount of energy in can absorb will also become 2 times higher. (The wider the block is, the higher maximum impact force would be. And if you make it two times longer, the maximum deformation will increase from 0.1 m to 0.2 m)

I also agree with Crabwhale.

Fiction doesn't have isolated chunks to destroy stuff most of the time so I don't know if that would even work out always. Not to mention that area of impact, pressure and angle of impact would also come into play here like Assalt and the others including myself have said, not just toughness (Which just adds a shitload more effort to deal with and would uproot our entire system). And that punching strength is measured mainly in force, not joules, with force already being a unit we can't even get to align with our energy system as is.
At the end of the day, like Crabwhale said, this is just a site for fun, and making things this complicated to understand becomes counterproductive and highly impractical to the point where it holds no advantage even if accurate by a small margin.
