Hardness v mechanical properties

[sgolds]

I'm looking into characterising a weld in FEA and have empirical results for hardness at the various points across a weld cross section. However, I am struggling to remember the relationship between Vickers hardness and the mechanical properties of the metal (E, G etc...). Can anyone enlighten me?

I can give you information on the tensile strength due to hardness from heat treating, not from welding. When dealing with welds, you have to be concerned with the heat effected area and all those wonderful little nuances.

From the Machinery's Handbook, 25th ed (pp530).
The tensile strength for Brinnell numbers up to 175 is
TS=B*515
The tensile strength for Brinnell numbers larger than 175 is
TS=B*490.

The Mach. Handbook also has conversions from Vickers hardness to Brinnell numbers. Look up the "hardness testing" section.
