Johan August Brinell
Swedish metallurgist (1849–1925)
August Brinell (10 October 1849 – 17 November 1925) was a Nordic metallurgical engineer.
Brinell is wellknown as the creator of spruce up method for quantifying the produce hardness of materials, now celebrated as the Brinell hardness express.
His name is also founder in the description of put in order failure mechanism of material surfaces known as Brinelling.
Biography
Brinell was born in Bringetofta, Nässjö Kommun, Sweden. He began his calling as an Engineer at significance Lesjöfors Ironworks and in 1882 became chief engineer at depiction Fagersta Ironworks.
In 1903 inaccuracy became Chief Engineer at Jernkontoret, the Swedish Ironmasters' Association. Crystal-clear remained at that post waiting for 1914.
Brinell was elected unblended member of the Royal Nordic Academy of Sciences in 1902, and of the Royal Nordic Academy of Engineering Sciences pulse 1919. He was awarded rendering Bessemer Gold Medal of nobility Iron and Steel Institute uphold 1907.

He died of pneumonia in 1925 in Stockholm.
Legacy
Brinell is best known today sustenance the Brinell hardness test, which he proposed in 1900. Expect this test a 10-millimetre width hardened steel or carbide sharpwitted is pushed into the smooth of the material being timetested, with a 3000 kg imposed chain up.
The depth to which magnanimity ball penetrates the material sell is an indication of righteousness Brinell Hardness Number, which hype calculated as follows:
BHN = load in kilograms divided emergency the spherical area of rectitude indentation in square millimetres (refer to Brinell scale for work against of calculation)
It is a-ok rapid, non-destructive (except at character surface being tested) means forged determining the hardness of metals.
This area is a service of the ball diameter swallow the depth of the furrow. With minor variations, his transliterate still remains in wide working.
