I read a few of the original Conan stories a little while ago. I was amazed at just how well the D&D armor class system emulated the feel of the stories. Regularly conan was saved from his injury by blows deflecting off his armor, helmet, and so on. They weren't partially stopped by his armor, as a "Armor as DR" system would create, they were completely deflected by it.
Actually, I like my own little take on this: Health & Resilience (which is actually just Wounds & Vitality with a few extras). In this, Armor provides Resistance and Absorption. Resistance fits the description you describe above (as it reduces Resilience/Vitality damage), while Absorption provides the standard reduction of wounds (and, if the damage rolled is low enough, still emulates the description from Conan and other literary sources).
(Note: In this system, Armor provides
nothing to Defense; indeed, your defense is weakened by the ACP of the armor.)
To emulate this effect with standard AC, you'd need to track two values: AC with armor and AC without. For example, if you are wearing a Chain Suit and have a Dexterity of 14, then the Attack roll needs to be determined against both values: 12 or less, the attack is dodged (10 + 2 Dex), while 13-17 means that the blow was deflected by the armor (+5 for the armor).
Unless, of course, the effect is relegated to arbitrary description, in which case
any system can emulate it.
