Just thinking,What would 60mm(a 20mm face plate riveted to a 40mm plate) of steel(with a tensile rating of either 350-400mpa or 450-500mpa) stand up to? Without seriously cracking, buckling, breaking or bending?

There's no such thing as "nothing left to draw" If you can down 10 pints and draw, you're doing alright by my standards

What do you mean stand up to? Tension? Compression? Shear strength?

Anything really-especially hard impacts

I'd assume quite a bit, considering your average unarmored ship's hull is about the same thickness of a dime, if I understand correctly.

Of course, materials engineering is just one component of how much of a beating a structure can take. We've discussed the advantages and disadvantages of "mercantile" vs "warship" construction and why many warships follow the former.

Well, it has no naval application, more of a large safe which the plates will be riveted to a heavy frame.

What's the type/grade of the steel?

From what I hear road plates, so pretty tough

Nathan Okun has some programs that calculate the performance of armor plate.
