About the large building level rating for M1 abrams

Where does it come from exactly? Is there a reliable source that confirms the statement?

"at most Large Building level in terms of total destruction (Comprised of up to 65,000 kilograms of "depleted uranium mesh-reinforced high-hardness steel-ceramic metal matrix composite armor" with a fragmentation energy of up to over 20 gigajoules)"

I have yet to update that (and I don't remember where the 20 GJ figure comes from, so feel free to remove that part), but here's what I have for the M60 Patton (which I haven't posted yet), which is lighter and has weaker armor than the M1 Abrams series, which I hope will help you understand how the Abrams would likely be Large Building level in terms of maximum possible durability.

M60 Patton:

Durability: At least Wall level+ (rolled homogeneous armor (RHA) has a Brinell hardness of up to 655, equal to a tensile strength of about 2210 megapascals), at most Building level+ in terms of total destruction (comprised of up to 51,890―52,160 kilograms of rolled homogeneous armor (RHA) with a fragmentation energy of 6.237―6.269 gigajoules)
While I haven't quite done the calculations for it yet, the "depleted uranium mesh-reinforced composite armor" of the M1 Abrams would be at least as strong in terms of its hardened steel content, and much harder due to the DU content, plus it's a minimum of ten tonnes heavier, so completely fragmenting an M1 Abrams hull should easily max out at Large Building level.

Does that clear things up?
 
Seems legit given those figures in pascals, though people who aren't familiar with how they would translate into joules might get thrown off by the rating.
 
I'm still working out the kinks in how to present this information, but I'm glad I was able to answer your question.
 
Total destruction durability is not used in versus bsttles, so yeah, it is likely need to be deleted
 
It's probably best kept as a calc methinks.

Also "depleted uranium mesh-reinforced composite armor" is actually called Chobham armor.
 
What is the density on this type of metal for the tanks? The mental density I used didn't yield nearly as high results, though I assume this has a higher density
 
If a character tanked a tank exploding to the point that it's in pieces, would that qualify for the 8-C-High 8-C rating for their durability?

Tank armor isn't just plainly ordinary steel, it's also ceramics and uranium-depleted armor as well so the density would indeed be higher.
 
But do you know what the density would be? That's the issue I'm facing. As I can't do any of the math on Feagging, V Fragging, Vaping, Ect without the density
 
Tried looking for the density of RHA armor but found nothing. Chobham armor is even more advanced than rolled homogenous armor and already has values for v. frag (2210 MPa according to the links above) but still no value for density.
 
RHA is steel armor, so it has the same average density as steel.
