Compute Brinell hardness BHN = 2F / [πD(D−√(D²−d²))] from test load F, indenter diameter D and indentation diameter d.
输入载荷 F、压头直径 D 与压痕直径 d,求布氏硬度。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Brinell hardness | HBW = 0.102·2F/(πD(D−√(D²−d²))) | Brinell 1900 / ISO 6506-1 |
| Test conditions | WC ball indenter, F/D² per material | GB/T 231.1 |
