A formula to calculate penetration

P= n * L * (square root of 1/2)

P-----------penetration
sortof-n---efficiency factor (APDSFS: 0.66, HEAT: 0.9)
L-----------length of the shot or jet
1----------- density of shot
2----------- density of armor


Also penetration statistics:

full-caliber shot: 1-2 times the caliber
APDS: 2-3 times the caliber
APDSFS: 3-4 times the caliber
High-class HEAT: 5-7, even 10 times the caliber

And, APDSFS ricochets if the hit angle is 10-15 degrees.

 

Armour Penetration Formula

Simple wargames-level formula:

and follow the links through "Stuff I Have Done" to "Mathematics for Wargamers".
Its my old site, haven't updated it for about 4 years, am now shifting everything over to http://www.cybamall.com/oli/home.html
but haven't got that swapped over yet.
It should be good enough for WWII, and I'm working on APFSDS etc at the moment.
The main problem is finding densities....
Stupid classified documents. :bang:

I just realised that Panzermeister's formula isn't any good! No I don't mean it like that, but it doesn't take into account impact velocity at all, I have a feeling that that formula is solely for hollow-charge waepons.
D'ohhh. How come I didn't notice that before?
