Small but important announcement: Willi Odermatt has updated his long rod calculator!
He has added some additional functions into the calculator on his website and he explains some of the nuances between penetrating a semi-infinite homogeneous RHA block vs an RHA plate array (http://www.longrods.ch/semi.php). The new calculator is more useful than ever, although now it no longer calculates the penetration of steel long rods, only their perforation limit.
I think everyone will find this very interesting and useful.
