Pyramid #3/52: Low-Tech II

On a non-chicken related subject, I was home sick today and spent my conscious hours tinkering with an Excel spreadsheet for the Low Tech Armor article, although I'm not sure if it'll work in older versions or GoogleDocs.

It brought up an interesting question though: What's the connection between physical statistics, DR/inch, Max DR, and WM for various materials? If I have a fantasy material that is "as hard as steel" but "as light as <x>" I can probably throw together DR/in (not used in any calculations that I've spotted) and WM (used) but Max DR (used) I am not sure how to generate.

It seems like it should be related to density (WM) and tensile strength or hardness (DR/in?), based on my not-a-materials-engineer vague impression? I tried fitting Max DR to a cube root and a log of DR/in and can't. Does being a flexible material factor in somewhere?
