Hardness v mechanical properties
Hardness v mechanical properties
(OP)
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?





RE: Hardness v mechanical properties
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.
