• Engineers can use hardness testing to verify the composition or heat-treatment history of materials. • Rockwell, Brinell, Vickers, and Shore are common hardness tests. Their use depends on the ...
IN the ball hardness test Meyer found that L =adn. By combining this relation with Brinell's formula H = L/A, it can be shown that the hardness number when the ball is immersed up to its diameter is ...
